A Comprehensive Study of the Magnetic White Dwarfs in DESI DR1
Adam Moss, Pierre Bergeron, Mukremin Kilic +2
As the end point of stellar evolution for most stars, white dwarfs offer powerful insight into stellar magnetism. Multiple formation channels are required to explain the observed p…
Searching for Massive Remnant Planetary System Hosts with White Dwarf Gaia XP Spectra
Lou Baya Ould Rouis, J. J. Hermes, Pierre Bergeron +5
Remnant planetary systems around massive white dwarfs () are intrinsically rare and remain poorly characterized. As the evolutionary endpoints of i…
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…
Synthetic Spectroscopy for White Dwarf Classification: Addressing Label Uncertainty and Class Imbalance
Olivier Vincent, Pierre Bergeron, Patrick Dufour
With the imminent data releases from next-generation spectroscopic surveys, hundreds of thousands of white dwarf spectra are expected to become available within the next few years,…
White Dwarf Merger Remnants: The DAQ Subclass
Mukremin Kilic, Pierre Bergeron, Simon Blouin +3
Four years after the discovery of a unique DAQ white dwarf with a hydrogen-dominated and carbon-rich atmosphere, we report the discovery of four new DAQ white dwarfs, including two…
