Atmospheric Temperature Inversions and He I 5876 Core Profile Structure in White Dwarfs
Beth Klein, Simon Blouin, Diego Romani +7
We report distinctive core profiles in the strongest optical helium line, He I 5876, from high-resolution high-sensitivity observations of spectral type DB white dwarfs. By analyzi…
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 Photometric and Spectroscopic Investigation of the DB White Dwarf Population using SDSS and Gaia Data
C. Genest-Beaulieu, P. Bergeron
We present a comprehensive analysis of DB white dwarfs drawn from the Sloan Digital Sky Survey, based on model fits to photometry and medium resolution spectroscopy from th…
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…
A comprehensive spectroscopic and photometric analysis of DA and DB white dwarfs from SDSS and Gaia
C. Genest-Beaulieu, P. Bergeron
We present a detailed spectroscopic and photometric analysis of DA and DB white dwarfs drawn from the Sloan Digital Sky Survey with trigonometric parallax measurements available fr…
Gaia Reveals Evidence for Merged White Dwarfs
Mukremin Kilic, N. C. Hambly, P. Bergeron +2
We use Gaia Data Release 2 to identify 13,928 white dwarfs within 100 pc of the Sun. The exquisite astrometry from Gaia reveals for the first time a bifurcation in the observed whi…
A study of the Lyman- line profile in DBA white dwarfs
C. Genest-Beaulieu, P. Bergeron
The hydrogen abundances in DBA white dwarfs determined from optical or UV spectra have been reported to differ significantly in some studies. We revisit this problem using our own…
Comparison of Atmospheric Parameters Determined from Spectroscopy and Photometry for DA White Dwarfs in the Sloan Digital Sky Survey
C. Genest-Beaulieu, P. Bergeron
We present a comparative analysis of atmospheric parameters obtained with the so-called photometric and spectroscopic techniques. Photometric and spectroscopic data for 1360 DA whi…
