Towards an Empirical Determination of the ZZ Ceti Instability Strip
A. Gianninas, P. Bergeron, G. Fontaine
We present atmospheric parameters for a large sample of DA white dwarfs that are known to be photometrically constant. For each star, we determine the effective temperature and sur…

Detailed Spectroscopic and Photometric Analysis of DQ White Dwarfs
P. Dufour, P. Bergeron, G. Fontaine
We present an analysis of spectroscopic and photometric data for cool DQ white dwarfs based on improved model atmosphere calculations. In particular, we revise the atmospheric para…

Discovery of Spectroscopic Variations in the DAB White Dwarf GD 323
C. Pereira, P. Bergeron, F. Wesemael
We report the discovery of spectroscopic variations in GD 323, the prototypical DAB white dwarf. Simultaneous optical spectroscopic observations over five consecutive nights of GD…
