Spectropolarimetric Survey of Hydrogen-rich White Dwarf Stars
A. Kawka, S. Vennes, G. D. Schmidt +2
We have conducted a survey of 61 southern white dwarfs searching for magnetic fields using Zeeman spectropolarimetry. Our objective is to obtain a magnetic field distribution for t…
Iron in Hot DA White Dwarfs
Stephane Vennes, Pierre Chayer, Jean Dupuis +1
We present a study of the iron abundance pattern in hot hydrogen-rich (DA) white dwarfs. The study is based on new and archival far ultraviolet spectroscopy of a sample of white dw…
LP 400-22, A very low-mass and high-velocity white dwarf
Adela Kawka, Stephane Vennes, Terry D. Oswalt +2
We report the identification of LP 400-22 (WD 2234+222) as a very low-mass and high-velocity white dwarf. The ultraviolet GALEX and optical photometric colors and a spectral line a…
Spectroscopic Identification of Cool White Dwarfs in the Solar Neighbourhood
Adela Kawka, Stephane Vennes
The New Luyten Two-Tenths catalog contains a large number of high-proper motion white dwarf candidates that remain to be spectroscopically confirmed. We present new spectroscopic o…
