A spectroscopic determination of the mass distribution of DA white dwarfs
TL;DR: In this paper, a mass distribution for a sample of 129 DA white dwarfs is presented, based on fitting hydrogen line profiles to the predictions of stellar atmosphere models, and the atmospheric parameters determined from spectroscopy are shown to be of improved accuracy over those obtained with other techniques.

TL;DR: In this paper, a detailed analysis of 108 helium-line (DB) white dwarfs based on model atmosphere fits to high signal-to-noise optical spectroscopy is presented.
Journal ArticleDOI
Atmospheric parameters of field subdwarf B stars
TL;DR: In this paper, high signal-to-noise ratio optical spectrophotometry of a sample of field subluminous B stars drawn largely from the Palomar Green ultraviolet-excess survey is analyzed with a new grid of model atmospheres and synthetic spectra.
Journal ArticleDOI
Optical and Ultraviolet Analyses of ZZ Ceti Stars and Study of the Atmospheric Convective Efficiency in DA White Dwarfs
Journal ArticleDOI
A Comparative Study of the Mass Distribution of Extreme-Ultraviolet selected White Dwarfs
TL;DR: In this article, the authors presented new determinations of effective temperature, surface gravity, and masses for a sample of 46 hot DA white dwarfs selected from the Extreme Ultraviolet Explorer (EUVE) and ROSAT Wide Field Camera bright source lists in the course of a near-infrared survey for low-mass companions.
