Close substellar companions suppress metal pollution in white dwarfs by a factor of 5.75 with 87% protection efficiency, backed by observations of 17 systems and N-body simulations.
A comprehensive public dataset of simulated Ariel exoplanet transmission spectra is released to benchmark detrending algorithms, with an ML baseline highlighting dataset shift risks.
Combined JWST spectra of Y dwarf WD 0806-661B fitted with ATMO 2020++ models give Teff 357 K, radius 1.08 RJup and mass 7 MJup, consistent with evolutionary models at 1.6 Gyr.
