Neural Posterior Estimation for White Dwarf Spectroscopic Characterization
Olivier Vincent, Patrick Dufour, Pierre Bergeron
White dwarf spectroscopic characterization is entering a big data era, with the number of spectroscopically characterized white dwarfs expected to grow from 100,000 to over 3…
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,…
The Solar Neighborhood. XXXIX. Parallax Results from the CTIOPI and NOFS Programs: 50 New Members of the 25 Parsec White Dwarf Sample
John P. Subasavage, Wei-Chun Jao, Todd J. Henry +9
We present 114 trigonometric parallaxes for 107 nearby white dwarf (WD) systems from both the Cerro Tololo Inter-American Observatory Parallax Investigation (CTIOPI) and the U. S.…
The Montreal White Dwarf Database: a Tool for the Community
P. Dufour, S. Blouin, S. Coutu +4
We present the "Montreal White Dwarf Database" (MWDD), an accessible database with sortable/filterable table and interactive plots that will, when fully completed, allow the commun…
Precise Atmospheric Parameters for the Shortest Period Binary White Dwarfs: Gravitational Waves, Metals, and Pulsations
A. Gianninas, P. Dufour, Mukremin Kilic +3
We present a detailed spectroscopic analysis of 61 low mass white dwarfs and provide precise atmospheric parameters, masses, and updated binary system parameters based on our new m…
SDSS J000555.90-100213.5: a hot, magnetic carbon-atmosphere WD rotating with a 2.1 day period
K. A. Lawrie, M. R. Burleigh, P. Dufour +1
A surprisingly large fraction (70%) of hot, carbon dominated atmosphere (DQ) white dwarfs are magnetic and/or photometrically variable on short timescales up to ~1000 s. However, h…
