Tentative CO detection from WASP-33b eclipse data alone with SPIRou validates stacking ingresses/egresses and shows Doppler eclipse mapping can constrain rotation with additional observations.
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.
A comprehensive public dataset of simulated Ariel exoplanet transmission spectra is released to benchmark detrending algorithms, with an ML baseline highlighting dataset shift risks.
