Products for "Hydrogen sulfide and metal-enriched atmosphere for a Jupiter-mass exoplanet"
<p>Data and model for JWST transit observation of HD 189733b using NIRCam (GO 1633, PI: Drake Deming) from paper "Hydrogen sulfide and metal-enriched<br>atmosphere for a Jupiter-mass exoplanet" (Fu et al. 2024).</p>
Spectrally resolved helium absorption from the extended atmosphere of a warm Neptune exoplanet
<p>Stellar heating causes atmospheres of close-in exoplanets to expand and escape. These extended atmospheres are difficult to observe because their main spectral signature – neutral hydrogen at ultraviolet wavelengths – is strongly absorbed by interstellar medium. We report the detection of the near-infrared triplet of neutral helium in the transiting warm Neptune-mass exoplanet HAT-P-11b using ground-based, high-resolution observations. The helium feature is repeatable over two independent transits, with an average absorption depth of 1.08±0.05%. Interpreting absorption spectra with 3D simulations of the planet’s upper atmosphere suggests it extends beyond 5 planetary radii, with a large scale height and a helium mass loss rate ≲ 3x10<sup>5</sup> g‧s<sup>−1</sup>. A net blueshift of the absorption might be explained by high-altitude winds flowing at 3 km‧s<sup>−1</sup>from day to night-side.</p>

Reproduction package for the paper: "Cold day-side winds shape large leading streams in evaporating exoplanet atmospheres"
<p>Supplementary material for the paper "Cold day-side winds shape large leading streams in evaporating exoplanet atmospheres" by Nail et al. (2024). <br><br>We provide the results of the 3D hydrodynamic simulation with Athena++, with key files including the input file and a snapshot from the simulation taken after 8 orbits for all models discussed in the paper. The post-processing is performed using a radiative transfer code found in the "post-process_HAT67" folder. This code, described by MacLeod & Oklopcic (2022), produces synthetic spectra from the simulation snapshots and has been enhanced for precise calculations in high-density regions. Additionally, a Jupyter notebook demonstrates how to analyze the data and create the figures presented in the paper.</p> <p>Note: In the new version of the paper, we use "dtaui = d['nhe3'] * d['dr'] * csi * Voigt(nu_cell, da1, natural_gamma)" in the Figures.ipynb notebook in cell 42. </p>
