The Potential of Multi-Colour Photometry for Pulsating Subdwarf B Stars
S. K. Randall, G. Fontaine, P. Brassard +1
We investigate the potential of multi-colour photometry for partial mode identification in both long- and short-period variable subdwarf B stars. The technique presented is based o…
A Search for Unresolved Double Degenerates Using IUE Archives
Charles-Philippe Lajoie, Pierre Bergeron
We present preliminary results of a study aimed at detecting double white dwarf systems using a method based on a comparison of optical and UV spectra for 141 DA stars drawn from t…
Comparison of White Dwarf Mass Determinations
S. Boudreault, P. Bergeron
White dwarf masses can be determined in several ways. Here we compare masses obtained from Balmer line spectroscopy with those derived from trigonometric parallax measurements for…
Analysis of DA White Dwarfs from the McCook & Sion Catalog
A. Gianninas, P. Bergeron, P. Dufour
The Sloan Digital Sky Survey has already doubled the number of spectroscopically identified white dwarfs. However, there remains a wealth of white dwarfs in the McCook & Sion catal…
On the Interpretation of High Velocity White Dwarfs as Members of the Galactic Halo
P. Bergeron, Maria Teresa Ruiz, M. Hamuy +4
A detailed analysis of 32 of the 38 halo white dwarf candidates identified by Oppenheimer et al. is presented, based on model atmosphere fits to observed energy distributions built…
