The White Dwarf Opportunity - Supplementary material

<p>Supplementary&nbsp;material for &#39;<em>The White Dwarf Opportunity: Robust Detections of Molecules in Earth-like Exoplanet Atmospheres with the James Webb Space Telescope</em>&#39;&nbsp;-&nbsp;ApJL&nbsp;(2020).</p> <p>This repository contains three figures, and full posterior probability distributions, corresponding to the modelling and retrieval analysis from Kaltenegger &amp; MacDonald et al. (2020).&nbsp;The supplementary materials are&nbsp;as follows:</p> <ul> <li><strong>WD_host_spectrum</strong>&nbsp;- comparison between the Sun&#39;s spectrum and the&nbsp;5000 K white dwarf spectrum used in our atmospheric models.</li> <li><strong>Mixing_ratio_profiles&nbsp;</strong>- calculated atmospheric mixing ratio profiles of H₂O, CH₄, O₃, CO₂, N₂O, CO, and CH₃Cl for an Earth-like planet in the white dwarf habitable zone.</li> <li><strong>PT_profile&nbsp;</strong>- calculated pressure-temperature (P-T) profile&nbsp;for an Earth-like planet in the white dwarf habitable zone.</li> <li><strong>Posterior_N_trans_...</strong>&nbsp;- full posterior distributions from the atmospheric retrievals corresponding to 1, 2, 3, 5, 10, 25, 50, and 100 transits with JWST&#39;s NIRSpec Prism.&nbsp;&nbsp;Each corner plot&nbsp;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 &plusmn;1&sigma; confidence levels are given. Otherwise, parameter constraints are expressed as 2&sigma; upper or lower bounds.</li> </ul> <p>For any questions, please contact: rmacdonald@astro.cornell.edu&nbsp;</p>
