A Constraint on brown dwarf formation via ejection: radial variation of the stellar and substellar mass function of the young open cluster IC2391
S. Boudreault, C. A. L. Bailer-Jones
Using the Wide Field Imager (WFI) at the ESO 2.2m telescope at La Silla and the CPAPIR camera at the CTIO 1.5m telescope at Cerro Tololo, we have performed an extensive, multiband…
The Mass Distribution of White Dwarfs: An Unwavering Obsession
P. Bergeron, A. Gianninas, S. Boudreault
We discuss some of our current knowledge of the mass distribution of DA and non-DA stars using various methods for measuring white dwarf masses including spectroscopic, trigonometr…
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 a Very Massive DA White Dwarf via the Trigonometric Parallax and Spectroscopic Methods
C. C. Dahn, P. Bergeron, J. Liebert +2
By two different methods, we show that LHS 4033 is an extremely massive white dwarf near its likely upper mass limit for destruction by unstable electron captures. From the accurat…
On the Purity of the ZZ Ceti Instability Strip: Discovery of More Pulsating DA White Dwarfs on the Basis of Optical Spectroscopy
P. Bergeron, G. Fontaine, M. Billeres +2
We report the discovery of two new ZZ Ceti pulsators, LP 133-144 and HE 1258+0123, selected on the basis of model atmosphere fits to optical spectroscopic data. The atmospheric par…
