Spectroscopic observations of high proper motion DA white dwarfs
E. Arazimova, A. Kawka, S. Vennes
We used the revised New Luyten Two-Tenths (rNLTT) catalog to select high proper motion white dwarf candidates. We studied the spectra of 70 hydrogen-rich (DA) white dwarfs, which w…

On the empirical evidence for the existence of ultra-massive white dwarfs
S. Vennes, A. Kawka
We re-examine the evidence for the existence of ultra-massive (M > 1.1 M_sun) white dwarfs based on gravitational redshift of white dwarfs in common proper motion binaries or in cl…

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…
