A Convective Dredge-Up Model as the Origin of Hydrogen in DBA White Dwarfs
B. Rolland, P. Bergeron, G. Fontaine
We revisit the problem of the formation of DB white dwarfs, as well as the origin of hydrogen in DBA stars, using a new set of envelope model calculations with stratified and mixed…
GALEX Absolute Calibration and Extinction Coefficients Based on White Dwarfs
Renae E. Wall, Mukremin Kilic, P. Bergeron +3
We use 1837 DA white dwarfs with high signal to noise ratio spectra and Gaia parallaxes to verify the absolute calibration and extinction coefficients for the Galaxy Evolution Expl…
A Magnetic White Dwarf with Five H Components
Mukremin Kilic, B. Rolland, P. Bergeron +3
G18335 is an unusual white dwarf that shows an H line split into five components, instead of the usual three components seen in strongly magnetic white dwarfs. Potential expl…
On the Measurement of Fundamental Parameters of White Dwarfs in the Gaia Era
P. Bergeron, P. Dufour, G. Fontaine +5
We present a critical review of the determination of fundamental parameters of white dwarfs discovered by the Gaia mission. We first reinterpret color-magnitude and color-color dia…
On the Spectral Evolution of Helium-Atmosphere White Dwarfs Showing Traces of Hydrogen
Benoit Rolland, Pierre Bergeron, Gilles Fontaine
We present a detailed spectroscopic analysis of 115 helium-line (DB) and 28 cool, He-rich hydrogen-line (DA) white dwarfs based on atmosphere fits to optical spectroscopy and photo…
