The White Dwarf Opportunity - Supplementary material
收藏资源简介：
Supplementary material for '<em>The White Dwarf Opportunity: Robust Detections of Molecules in Earth-like Exoplanet Atmospheres with the James Webb Space Telescope</em>' - ApJL (2020). This repository contains three figures, and full posterior probability distributions, corresponding to the modelling and retrieval analysis from Kaltenegger & MacDonald et al. (2020). The supplementary materials are as follows: <strong>WD_host_spectrum</strong> - comparison between the Sun's spectrum and the 5000 K white dwarf spectrum used in our atmospheric models. <strong>Mixing_ratio_profiles </strong>- calculated atmospheric mixing ratio profiles of H<sub>2</sub>O, CH<sub>4</sub>, O<sub>3</sub>, CO<sub>2</sub>, N<sub>2</sub>O, CO, and CH<sub>3</sub>Cl for an Earth-like planet in the white dwarf habitable zone. <strong>PT_profile </strong>- calculated pressure-temperature (P-T) profile for an Earth-like planet in the white dwarf habitable zone. <strong>Posterior_N_trans_...</strong> - full posterior distributions from the atmospheric retrievals corresponding to 1, 2, 3, 5, 10, 25, 50, and 100 transits with JWST's NIRSpec Prism. Each corner plot depicts correlations between pairs of retrieved parameters and marginalised histograms for each parameter. Where parameters have clear upper and lower bounds, the median retrieved values and ±1σ confidence levels are given. Otherwise, parameter constraints are expressed as 2σ upper or lower bounds.

本数据集为论文<em>The White Dwarf Opportunity: Robust Detections of Molecules in Earth-like Exoplanet Atmospheres with the James Webb Space Telescope</em>——《天体物理学杂志快报》（Astrophysical Journal Letters, ApJL）2020年刊的补充材料。本仓库包含Kaltenegger与MacDonald等人（2020）的建模与大气反演分析所得到的三张图表及完整后验概率分布。补充材料具体如下： <strong>WD_host_spectrum</strong>：太阳光谱与本研究大气模型中采用的5000开尔文白矮星光谱的对比图。 <strong>Mixing_ratio_profiles</strong>：白矮星宜居带内类地行星的H₂O（水）、CH₄（甲烷）、O₃（臭氧）、CO₂（二氧化碳）、N₂O（一氧化二氮）、CO（一氧化碳）以及CH₃Cl（氯甲烷）的计算大气混合比廓线。 <strong>PT_profile</strong>：白矮星宜居带内类地行星的计算压强-温度（P-T）廓线。 <strong>Posterior_N_trans_...</strong>：对应詹姆斯·韦布空间望远镜（James Webb Space Telescope, JWST）近红外光谱仪棱镜（NIRSpec Prism）模式下1、2、3、5、10、25、50和100次凌星事件的大气反演全后验分布。每张三角图（corner plot）均展示了反演参数间的相关性，以及各参数的边缘化直方图。若参数存在明确的上下界，则会给出反演得到的中位数值及±1σ置信区间；其余参数约束则以2σ上下界形式呈现。 如有任何疑问，请联系：rmacdonald@astro.cornell.edu
