Stark Broadening and White Dwarfs [PDF]
Open Astronomy, 2011 White dwarf and pre-white dwarfs are the best types of stars for the application of Stark broadening research results in astrophysics, since in the atmospheres of these stars physical conditions are very favorable for this line broadening mechanism - in ...

Asteroseismology of DAV white dwarf stars [PDF]
Open Astronomy, 1998 Following the recent mode identification by Clemens suggesting the hydrogen layer mass of the DAV (ZZ Ceti) stars is nearly the same, I make the extreme assumption that models with a single composition profile with a hydrogen layer mass of 1.5 × 10−4M* may be able to fit the observed pulsation periods.

White dwarf and subdwarf stars in the Sloan Digital Sky Survey Data Release 14 [PDF]
Monthly Notices of the Royal Astronomical Society, 2019 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.

Hot DAVs: a probable new class of pulsating white dwarf stars [PDF]
Monthly Notices of the Royal Astronomical Society, 2013 We have discovered a pulsating DA white dwarf at the lower end of the temperature range 45 000–30 000 K where a few helium atmosphere white dwarfs are known. There are now three such pulsators known, suggesting that a new class of theoretically predicted

Monthly Notices of the Royal Astronomical Society, 2011 The surface abundances of extreme helium (EHe) and R Coronae Borealis (RCB) stars are discussed in terms of the merger of a carbon-oxygen white dwarf with a helium white dwarf.

White-Dwarf Asteroseismology With the Kepler Space Telescope
Frontiers in Astronomy and Space Sciences, 2020 In the course of their evolution, white-dwarf stars go through at least one phase of variability in which the global pulsations they undergo allow astronomers to peer into their interiors, making it possible to shed light on their deep inner structure ...

A Chondritic Solar Neighborhood
The Planetary Science Journal, 2023 A persistent question in exoplanet demographics is whether exoplanetary systems form from similar compositional building blocks to our own. Polluted white dwarf stars offer a unique way to address this question, as they provide measurements of the bulk ...

Catalog of Magnetic White Dwarfs with Hydrogen Dominated Atmospheres
The Astrophysical Journal, 2023 White dwarfs are excellent research laboratories as they reach temperatures, pressures, and magnetic fields that are unattainable on Earth. To better understand how these three physical parameters interact with each other and with other stellar features,
