Stark-Broadened Profiles for Ionized Helium Lines Using Computer Simulations
Patrick Tremblay, Alain Beauchamp, Pierre Bergeron
We present new and improved calculations of Stark-broadened profiles for ionized helium, a key ingredient in the spectroscopic analysis of helium-atmosphere DO white dwarfs. Our ap…
A Theoretical Investigation of He I Line Profiles for the Spectroscopic Analysis of DB White Dwarfs
Patrick Tremblay, Pierre Bergeron, Alain Beauchamp
We present a comprehensive investigation of He I line profile calculations used in the spectroscopic analyses of DB white dwarfs. Our study includes an in-depth photometric and spe…
Improved Stark Broadened Profiles for Neutral Helium Lines Using Computer Simulations
Patrick Tremblay, Alain Beauchamp, Pierre Bergeron +1
The study of Stark broadening of neutral helium lines, despite significant advances over recent decades, has not led to updated large grids of helium line profiles relevant to the…
New Calculations of Stark Broadened Profiles for Neutral Helium Lines Using Computer Simulations
Patrick Tremblay, Alain Beauchamp, Pierre Bergeron
We present new calculations of Stark broadened profiles for neutral helium lines using computer simulations that include some important aspects aimed at better representing the dyn…
A Comprehensive Spectroscopic Analysis of DB White Dwarfs
P. Bergeron, F. Wesemael, Pierre Dufour +9
We present a detailed analysis of 108 helium-line (DB) white dwarfs based on model atmosphere fits to high signal-to-noise optical spectroscopy. We derive a mean mass of 0.67 Mo fo…
Multiwavelength Observations of the Hot DB Star PG 0112+104
P. Dufour, S. Desharnais, F. Wesemael +8
We present a comprehensive multiwavelength analysis of the hot DB white dwarf PG 0112+104. Our analysis relies on newly-acquired FUSE observations, on medium-resolution FOS and GHR…
