18-year monitoring finds stable metal line strengths and accretion rates in four of five polluted white dwarfs over hundreds to thousands of diffusion timescales.
Post-processing of 44-year adiabatic 3D simulations of common envelope events yields lightcurves with a 3-5 year hot peak from photosphere expansion, dust formation after 1-3 years causing bolometric decline and 400 K plateau, plus predictions of optical thinning in 100-200 years, matching some obse
Model atmosphere fitting of 25,642 cool white dwarfs in DESI DR1 finds no photometric-spectroscopic mass discrepancy for DAs, magnetic DAs at all temperatures, increasing H/He ratios in He-atmosphere stars below ~10,000 K, and a rising He-atmosphere fraction due to convective mixing.

A Detailed Model Atmosphere Analysis of Cool White Dwarfs in DESI DR1
