Products and Models for "Volatile-to-sulfur Ratios Can Recover a Gas Giant's Accretion History"
<p>The newfound ability to detect SO2 in exoplanet atmospheres and presents an opportunity to measure sulfur abundances and so directly test between competing modes of planet formation. To explore the detectability of SO2 in<br> transmission spectra and its ability to diagnose planet formation, we present a grid of atmospheric photochemical models and corresponding synthetic spectra for WASP-39b (where SO2 has recently been detected). Our grid contains 2,662 model atmospheres: spanning 1-100x the solar abundance ratios of C, O, and S (11^3 combinations of abundances) and for two thermal profiles: corresponding to the morning and evening terminators. We also provide 3,993 synthetic spectra: one for each of the morning and evening terminators, plus a set of spectra that are the<br> mean of the morning and evening spectra (corresponding to the transmission spectrum that would be observed during transit).</p> <p>If you use these files, please cite Crossfield (2023).</p> <p> </p> <p>The transmission spectra are simple two-column CSV files -- wavelength in microns, and transit depth. The model atmospheres are in Python pickle format, and are the standard output of the VULCAN photochemistry code. The several data sets are:</p> <ul> <li>wasp39_mean_spectra.tar.gz -- average terminator spectra. <strong>Use this for comparing to full-transit observations.</strong></li> <li>wasp39_morning_spectra.tar.gz -- spectra corresponding to the morning-terminator models.</li> <li>wasp39_evening_spectra.tar.gz -- spectra corresponding to the evening-terminator models.</li> <li>wasp39_evening_profiles.tar.gz -- model atmospheres and chemical profiles for the evening-terminator thermal profile.</li> <li>wasp39_morning_profiles.tar.gz -- model atmospheres and chemical profiles for the morning-terminator thermal profile.</li> </ul> <p>All filenames are of the form</p> <p>wasp39b_tsai23-Kzz_SNCHO_10x_z83_C7.5_N10.0_O100.0_S18.0__morn_transmission.csv</p> <ul> <li>wasp39b -- planet name</li> <li>tsai23-Kzz -- using Kzz (eddy diffusion) profile from Tsai et al.

Simulation data files of the article: "Gas accretion damped by dust back-reaction at the snowline"
<p>We make available here the simulation output files used in the paper "Gas accretion damped by dust back-reaction at the snowline" by Gárate et al. (submitted to A&A). The simulation shows the gas and dust evolution of a protoplanetry disk around the snowline, considering the dust back-reaction.</p> <p>The simulations were performed using TwoPopPy (Birnstiel et al, 2012) to solve the advection of gas and dust.</p> <p>Each file corresponds to one simulation. Each files contains the radial profile of the physical properties at different snapshots.</p> <p>The simulation data is saved in numpy format. We include the jupyter notebook as a guide of how to read and plot the simulation files.</p>
