Characterising the Atmosphere of Proxima B

Characterising the Atmosphere of Proxima B 1.Intro As of April 2016, 582 extrasolar planets have been discovered (NASA) using Doppler spectroscopy, a method for detecting extrasolar planets by deducing their radial velocity from the Doppler shifts in the spectrum of the planets parent star. Using this method, Anglada-Escude et al (2016) recent observations have revealed a 1.3 Earth mass planet orbiting the red dwarf Proxima Centauri. Although Earth-like planets arent uncommon, the recent discovery of Proxima b is particularly exciting as at a distance of 1.3 parsecs it is our closest potentially habitable star. Where previous studies were stunted by the distance of the host star to the Earth, Proxima b may within reach of Earth and space based telescopes giving us the ability to better judge its characteristics. While Proxima b is in the goldilocks zone, meaning it has potential to have water and perhaps even life, it is subject to intense radiation and solar wind. The habitability of Proxima Centauri b and Prospects for characterising the atmosphere of Proxima Centauri b question whether Proxima has an atmosphere, with the primary focus being whether Proxima b can maintain liquid water on its surface. The former does this by estimating the current high-energy irradiance of the planet and show that the orbit is likely to be in either a synchronous or 3:2 spin-orbit resonance. The latter article considers measuring the variation in thermal emission with orbital phase as a method for characterizing Proxima bs atmosphere. 2. The habitability of Proxima Centauri b 2.1 SummaryIn this paper the authors work through a number of factors that could affect the potential habitability of Proxima b. While noting there is a surplus of Earth like planets (Kepler), the authors need question whether Proxima lies within the Habitable Zone, where a stellar flux is low enough to maintain surface water but high enough to maintain the planetary surface as defined by Kasting et al. Due to a stellar input of ~65% than of the Earth Proxima b lies within these limits. High Energy IrradiationHigh-energy emissions including X-rays through to far-UV (FUV) and particle winds are known to influence atmospheres of rocky planets. A particular issue when estimating the XUV fluxes is that Proxima is a flare star (haish et 1983) meaning its HE emissions can vary significantly. The work in the paper was built from X-ray emission observations via ROSAT and XMM that report log LX = 27:2 erg sà ´Ã¢â€š ¬Ã¢â€š ¬Ã¢â€š ¬1 g and LX = 27:4 erg sà ´Ã¢â€š ¬Ã¢â€š ¬Ã¢â€š ¬1 respectively (Haish 1999). To generalise the overall dose on the planetary atmosphere, the authors consider the average XUV luminosity over an extended timescale while accounting for flare variation. Using XMM-Newton observations, the strongest flare has an energy of about 210^31 erg. CN Leo has a similar X-Ray luminosity and thus can be used to model flare distribution for Proxima. Audard el state a power law with the form N(> E) = 3:7 _ 1037Eà ´Ã¢â€š ¬Ã¢â€š ¬Ã¢â€š ¬1:2, where N is the number of flares per day, and E is the total (integrated) flare energy in erg . This shows CN Leo has flares with energies greater than about 2 _ 1031 erg over a timescale of 1 day.This is found to be in agreement with the XMM-data set, consolidating this is a reliable representative of the daily flux. Thus giving (between 0.65 and 3.8nm) a time integrated average flux of 87 ergss_1cm^-2 . To account for more energetic flares a calculated extra 22 ergs s^-1 cm^-2 is added, totalling at 109 erg s^-1cm^-2 . Flux estimates (including flare contribution) were calculated over a range of wavelengths, as listed below: ROSAT observations for the 3.8nm to 10nm range produced an X-Ray dose of 163 erg s^1 cm^2 EUVE spectrum for the extreme UV 10nm to 40nm range produced a flux value of 111 ergs^1cm2 FUSE observations for the far UV 92-118nm range produced a flux value of 20 egs HST/STIS for the 118-170nm range produced a flux value of 130 ergs Therefore between 0.6 and 118nm, the total integrated flux today that is a fair representative of HE radiation on the atmosphere of Proxima b is of 307ergs^1. For comparison purposes, the XUV flux at Earth is calculated to be 5.1 ergs, showing Proxima b to receive 60 times more XUV flux. This data is illustrated in fig. -Probability of capture: The authors remark on the poor parameterizations of previous work on tidal dissipation of rocky planets (Darwin 1880, love 1909, goldreich 1963), their primary issue being models would always predict an equilibrium rotation rate where tidal torque would vanish. The authors use the Andrade model as tailored by Efromsky 2012 and Eq 10 of Marakov 2012. The Andrade time was set to be equal to the Maxwell time of tm=500yr for simplicity. The results for 3:2 resonance capture probability are shown in fig. Curve a) indicates where tidal torque at the lower boundary of the separatrix is negative and greater than the maximum restoring torque. b) indicates tidal torque at the lower boundary of the separatrix is positive and (c) indicates where maximal tidal torque inside the resonance is greater than the maximum triaxial torque. Regions above (c) and/or (b) (white regions) leads to certain capture due to tidal torque, whereas below (c) and (a) (black region) capture is impossible as triaxial torque is too weak. The implication for climate would be that liquid water is possible depending on the rotation. If the planets orbital eccentricity is 0.06 it is likely Proxima will have a tropical belt. -water loss It is undeniable how estimates of volatile loss are poorly constrained, due to the lack of key data e.g. evolution of atmospheric composition, stellar wind properties, photochemistry of the upper atmosphere etc. The authors take a moment to discuss an alternative approach for determining Proxima bs volatile loss: Comparing Earths early development with Proxima bs. By considering how Earth built by a multitude of moon size protoplanets across 10Myr, the authors argue the XUV irradiation and stellar wind experience on proto-Earth is comparable to that of Proxima b. lamer et al modelled volatile losses of early Earth showing significant loss caused by hydrodynamic escape of hydrogen and strong stellar wind exposure. Due to the fact the runaway phase of Proxima is only longer than the Earths by a small factor 12 um. Finally, to determine how tightly the albedo and heat redistribution can be constrained, an MCMC fit was trailed on the simulated LRS spectrum from Fig 2 using the emcee package (Foreman-Mackey et al) The fit was run with redistribution, F, and albedo, A, as free parameters, from the fit one can measure F=0.07 and albedo A=0.13 to be well constrained. The authors conclude that a MIRI phase curve is sufficient means to determine the existence of an atmosphere on Proxima b. A then turn their attention to the feasibility of detecting an ozone absorption feature from Proxima b at 10um. Key motivation being this is a prominent feature of Earths IR emission spectrum and acts a potential evidence of present life. Bond albedo was set to A=0.3 to match Earths and an isothermal temperature arrangement is assumed. Using a modelling calculated by Rugheimer, that assumes an Earth-like atmospheric composition irradiated by a GJ 1214b-like star, it is noted that the ozone feature does not vary with planet orbital phase but is detectable from a very high signal-to-noise spectrum. The predicted feature amplitude was less than 1ppm. To illustrate how much observation time would be required to detect said feature, fig shows a simulated spectrum co-added from 60 days. The absorption feature at 9.8um corresponds to an ozone band and the dip at 8 is due to methane. 3.2 Implication/ImportanceA major concern would be that detecting modulations with JWST would be extremely challenging due to Proxima Centauri s stellar variability and flares. To estimate how feasible it would be to detect Proxima bs thermal emission, the JWST Exposure Time Calculator (ETC) was used to estimate signal-to-noise ratios for MIRI observations of Proxima Cen. Using a model spectrum, the ETC produced the expected count rate, which also correlated with the S/N predictions from Cowan et al. Although it feeds back good results, the paper highlights the need to test the precision of the MIRI detector. A general issue with this paper is calculations are simply based on possible observations with the James Webb Space Telescope, as opposed to actual recorded data. Realistically, conclusions drawn about phase variation for Proxima arent definitive, though the paper shows potential of the MIRI could do and show. Other recent paper including à ¢Ã¢â€š ¬Ã‚ ¦.., have a general agreement that the JWST could be used to infer exoplanets rotation periods and dissipation rates. In theory, measurement using the MIRI (which covers the wavelength range of 5 to 28 microns) at different wavelengths could be used to find atmospheric signatures, constrain the radius, the albedo and the inclination of Proxima b, as well as its rotation. This paper consolidates this idea. 3.3 Assessment In the introduction many issues that could affect Proxima bs atmosphere are mentioned, for example Proxima bs evolutionary history, but these topics werent covered in the body of the article. The introduction also states three methods available to characterize the planets atmosphere. The last (measure variation in thermal emission with orbital phase) is the focus of this paper, however the first two (directly image the planet, measure variations in reflected starlight with orbital phase) were perhaps unreasonably undiscussed. The quality of the results is difficult to assess, on the one hand an abundance of assumptions were used, to the extent that all of Section Five of this paper lists assumptions about the planetary system used in the their analysis. In many cases decisions were poorly explained. For example an albedo of 0.1 is used in the climate model while commenting Proxima bs atmosphere would likely have a higher albedo (perhaps 0. Like Earths), however dont they elaborate on why they settled with 0.1. On the other hand many of the assumptions were heavily based on previous work by a variety of researchers. The need for atmosphere case with moderate distribution F=0.35 was driven by a plethora of research ((e.g., Joshi et al. 1997; Merlis Schneider 2010; Heng et al. 2011a, 2011b; Pierrehumbert 2011; Selsis et al. 2011; Leconte et al. 2013; Yang et al. 2013, 2014; Koll Abbot 2015, 2016; Turbet et al. 2016).) which have shown how the presence of an atmosphere can reduce the amplitude of IR phase v ariation by a factor two or more. This made decisions feel more reliable and justified. Yet, without having read referenced work, certain aspects were hard to follow. Some of their most significant work on simulated spectrum is noted to be built upon the work of selsis et al, however there is no indication of what work Sel actually conducted. The paper in general couldve done with a more substantial amount of explanation for this made for a frustrating read. 4. Comparison In terms of writing style, It is apparent anglada had done a more extensive amount of research, Work is important as it highlight the value of using a combination of space and ground telescopes and In terms of research, both papers take a focus on the effects of different eccentricities on a tidally locked planet and its atmosphere. K considered this when creating a climate model and simulated a measurement of the thermal phase variation whereas anglada deduced it is likely Proxima is in a 3:2 rotation and considered the implication of the HE radiation Proxima b would receive. Generally, the authors draw the same conclusion, that Proxima b could have an atmosphere, perhaps capable of supporting life. In the case of no heat redistribution or having synchronous rotation, Proxima b having an atmosphere is improbable. In the case or heat redistribution or asynchronous rotation, one could infer that an atmosphere or ocean is present. Theres a consensus that defining planet habitability is not straightforward, there are vast limitations on calculations that can be done and any modelling is not strongly representative of Proxima bs characteristics. Both papers also make use of modelling Earths past and current state as a forecast for Proxima bs development. Using the Earths past to give us more information to further determine Proxima bs atmosphere and potential habitability was fairly clever and intuitive concept. Future work, perhaps after the launch of the JWST, could consider this concept in more detail for a more well-rounded understanding of Proxima bs characteristics.In conclusion, both papers were particularly insightful, encourage future missions similar to Kepler, and will hopefully drive new research.

Cultural Dimensions Essay

Culture is one of those terms that have no specific definition because of its diverse nature. It can be looked at from any point of view. However, a basic definition that includes all the important aspects of a culture is ‘the integrated pattern of human knowledge, belief, and behavior that depends upon the capacity for learning and transmitting knowledge to succeeding generations’ (Webster, 2008). Culture is very important if one wants to study a society. It can tell a lot about different aspects of the society and this is the reason why different countries deal with issues differently. This paper will outline and discuss the cultures of China, Saudi Arabia and United States of America and will show how, because of differences in cultures, issues like strategy, team communications, influence tactics, conflict management etc are dealt differently in these countries. Towards the end, recommendations to avoid cross cultural differences will be outlined. United States of America The population of United States of America is very diverse. It has people from many backgrounds. However in general, the American culture is said to be one of the most individualistic culture in the world. This means that people are less integrated in forms of groups. They do not depend on each other and are more concerned about themselves than about others. The country also has a higher than world average score for masculinity. This means that there is differentiation between genders to some extent in the American culture. On the other hand, the score in power distance dimension shows that there are not many differences in societal levels. This can be seen in organizational, family or governmental settings. People expect that power will be distributed equally to a greater extent even if someone is lower in the level of hierarchy. Besides this, the score on uncertainty avoidance is also lower than the world average. This means that people are tolerant to uncertainty and there are few rules and regulation present to control results (Hofstede, 2003). One important characteristic about the work culture in United States is that hard work and integrity is appreciated and also, punctuality is valued. Both mean and women are expected to dress according to the surroundings, situation and weather. The culture does not promote or support gift giving in business as it may be considered as bribe (International Business Center, 2003). As mentioned above, because of the cultures individualistic nature, privacy is valued. The lifestyle in general is causal and informal. Americans believe in voicing their opinions and although this direct speaking is sometimes considered as rude in other cultures, it is totally normal among Americans (American Graduate Education, 2007). From the above details, we can tell a lot about how issues like strategy, team communications, influence tactics and conflict management get affected. Since people believe in voicing their opinions, the strategy is usually bold. In addition to this, since any kind of strategy requires its actors to put in all the effort they can possible put in. Be it in an organization, government or even in one’s personal life. The team communication is very effective because of the low power distance characteristic and informal nature of the American culture. The belief that the power distributed to everyone is equal and the informal nature in groups inhibits any kind of barrier in effective teamwork. Gift giving or anything close to bribery is considered very insulting and inappropriate therefore this approach is not widely used in influence tactics. Conflict management is usually done openly without an arbitrator or a third party (American Graduate Education, 2007). As mentioned above, Americans believe in voicing their opinions so this plays a major role in conflict management strategies used nationwide. In order to remove the communication barriers, in my opinion, one would not have to change much about himself because of the presence of a diverse cultures in the population. However, it is suggested that English is used to communicate any kind of verbal information as this is understood and accepted by almost everyone (American Graduate Education, 2007). Regarding dressing, one is suggested to dress appropriately considering the time of the day, weather, occasion and gathering. China Now we come to the Chinese culture. The culture of the people of China is very different from the American culture just discussed above and it is said to be the exact opposite of the America culture. In fact, the Chinese culture is very different, unique and peculiar if one compares it with the rest of the cultures in the world. It is difficult to understand for those who are not a part of it however one does not need to completely understand it before blending in (Think Quest, 1998). We will now look into this in detail. We can prove the above hypothesis correct by comparing the individualism dimension of the American and Chinese cultures. Unlike the America culture, the people of china are very collectivistic. They are integrated tightly, they look after each other and they are highly dependable on the people around them. This can be seen in their family structures and organization values etc. Both the Chinese and American cultures are similar when it comes to the Masculinity dimension. They both score approximately 68 on a scale of 1 to 100. This again is higher than the world average which means that there are slightly more differences between genders in the Chinese culture compared to the rest of the world. The uncertainty avoidance is slightly higher than United States which means people are more tolerable to not have complete information as compare to the American culture. The fourth dimension of Power Distance is also quite higher than the United States meaning that people expect more differences in organizational hierarchies. The American score on Power distance was 45 while the Chinese score is 85 therefore one can imagine the amount of differences in the structures of organizations, governmental institutions and families etc. One major difference is in the long term orientation dimension of the two cultures. While the American culture was more on the lower side of this dimension, the Chinese culture is known to have the highest ranking factor when it comes to long term orientation. These means that people tend to overcome obstacles with time and not with will and strength (Hofstede, 2003). Some other important details of the Chinese culture include being used to the communist form of government. The Chinese culture is very hospitable and accepts people from all backgrounds. Since there is no one particular religion that is followed in the country, anyone can adjust easily (International Business Center, 2003). All these cultural characteristics largely influence many issues in business. For instance any strategy usually requires everyone to stick together and work collectively because of the collectivistic nature of the culture and also teamwork is very effective as people realize that they are dependent on each other. However, because of high power distance, both strategy and team communication is affected. Communication within team becomes more broken as it has to be passed through several levels of hierarchy. The cultural values are imbedded in the he influence tactics. For example these tactics project the idea of togetherness as it is evident from their advertisements that promote family ties and bonds etc (Lin, 2001). The approach to conflict management is including a third party to settle issues. In order to remove the communication barriers, a few things need to be kept in mind. Firstly, it is suggested to not use too much of hand movements as this distracts the audience. Besides this, there are other non verbal gestures that must be avoided. For instance pointing finger may be considered rude therefore such things must be kept in mind in order to ensure effective communication. English is understood widely in the corporate world therefore this is preferred after Chinese of course (International Business Center, 2003). Saudi Arabia Now we will start discussion on the culture of the last country of the paper. This country has also been selected to be studied because of its different and unique culture. The Chinese and Arabian Cultures are similar in the power distance dimension of their cultures. Unlike the American Cultures, the high power distance ranking indicates the inequality of wealth throughout the Arab world. Because of this, the rich of course have more power than the poor. The uncertainty avoidance dimension of the Arabian culture is also very different from the Chinese and the American cultures. While the Chinese and Americans ranked lower than world average on the uncertainty avoidance ranking, the Arabian culture has a higher score in this dimension. Meaning that people do not tolerate uncertainty at all and this can be the reason why there are so many rules, policies and regulations are implemented in the country. Surprising as it may sound, the Arabian culture scored low on the masculinity dimension considering all the restrictions on the Arabian women etc. The score was 52 which is only slightly higher than the world average. The reason for low masculinity ranking could be that all the restrictions on the women of the country are because of the religion and not the culture. The Arabian culture, like the Chinese culture, is more collectivistic. It had an average ranking of 38 which is way lower than that of the American culture and also the world average for that matter. This means people prefer to stick together and remain integrated (Hofstede, 2003). The Arabic culture is largely shaped by its history and religion (Saudi Embassy, 2006). Therefore history, religion and language are valued the most in the Arabian culture. These cultural characteristics affect many practical issues. The strategy devised by Arabs in any situation usually calls for people to remain cohesive. Also because of high uncertainty avoidance, there are many rules, regulations and policies that must be followed. Because of high power distance, like the Chinese culture, effective team communication is affected. But on the other hand, this is compensated for because of collective nature of the culture. The influence tactics are devised keeping the religion in mind. Anything such as bribery or use of women models in advertisements are avoided because this is against Islam. Conflicts are also managed according to the rules of Shari’ah which is the Islamic or Sacred Law (Hooker, 1996). Also, because of the collectivistic nature of the culture a third party is often included in managing conflicts. There are many cultural traits that must be kept in mind in order to improve communication. Firstly, one must keep in mind that during communication, anything he says or does not offend or insult Islam. The people are very sensitive when it comes to the religion therefore one must dress, talk and behave appropriately. There are certain non verbal gestures that are considered offensive such as the thumbs up sign and crossing of legs etc. Therefore one should avoid these. Arabic is preferred by the people there therefore it is preferred is one communicates or at least uses some words from Arabic. One must not ask too many questions are the inquisitive one is considered as the most unimportant and lastly, if an Arab offers a gift, not accepting it may be considered offensive (International Business Center, 2003).
