White dwarf and subdwarf stars in the Sloan Digital Sky Survey Data Release 14
read the original abstract
White dwarfs carry information on the structure and evolution of the Galaxy, especially through their luminosity function and initial-to-final mass relation. Very cool white dwarfs provide insight into the early ages of each population. Examining the spectra of all stars with $3\sigma$ proper motion in the Sloan Digital Sky Survey Data Release 14, we report the classification for 20 088 spectroscopically confirmed white dwarfs, plus 415 hot subdwarfs, and 311 cataclysmic variables. We obtain Teff, log g and mass for hydrogen atmosphere white dwarf stars (DAs), warm helium atmosphere white dwarfs (DBs), hot subdwarfs (sdBs and sdOs), and estimate photometric Teff for white dwarf stars with continuum spectra (DCs). We find 15793 sdAs and 447 dCs between the white dwarf cooling sequence and the main sequence, especially below Teff= 10000 K; most are likely low-mass metal-poor main sequence stars, but some could be the result of interacting binary evolution.

First planetesimals from DESI DR1: 12 highly metal-rich white dwarfs
Twelve white dwarfs from DESI DR1 have accreted debris resembling inner-Solar-System rock, with two systems likely accreting water-rich planetesimals.

Observing bright pulsating white dwarfs with PLATO: A new window into the late stages of stellar evolution
PLATO should detect white-dwarf pulsation modes down to about 0.1 milli-magnitudes for bright targets, and the LOPS2 field contains 159 high-priority white-dwarf candidates for such measurements.

Constraints from parallaxes and average period spacings in the asteroseismic study of 8 DAVs
Asymptotic period spacings plus Gaia parallaxes favor thick hydrogen layers in most of eight DAVs and give an upper limit M_env ≲ 10^{-2.2} for the helium-layer base.
