New MAROON-X observations of HAT-P-70b detect multiple neutral and ionized metals with day-to-night wind signatures and demonstrate that ionization-aware retrievals yield abundance ratios closer to solar values except for enhanced nickel.
An open-source GCE code with a 100x faster solver demonstrates that refractory ratios Mg/Si and Fe/Si control carbon partitioning and atmospheric properties in water-accreting sub-Neptunes.
Hycean models with a 1-bar H2 envelope, percent-level CH4 and CO, and CO2 at 10^-3 to 10^-2 reproduce the 0.8-5.2 μm JWST spectra of K2-18b.
A comprehensive public dataset of simulated Ariel exoplanet transmission spectra is released to benchmark detrending algorithms, with an ML baseline highlighting dataset shift risks.
