Data-Driven Selection and Spectral Classification of White Dwarf Stars
Olivier Vincent, Pierre Bergeron, Patrick Dufour
The next generation of spectroscopic surveys is expected to provide spectra for hundreds of thousands of white dwarf (WD) candidates in the upcoming years. Currently, spectroscopic…
A Spectro-photometric Analysis of Cool White Dwarfs in the Gaia and Pan-STARRS Footprint
Alexandre Caron, Pierre Bergeron, Simon Blouin +1
We present a spectro-photometric analysis of 2880 cool white dwarfs within 100 pc of the Sun and cooler than Teff = 10,000 K, with grizy Pan-STARRS photometry and Gaia trigonometri…
On the Nature of Ultracool White Dwarfs: Not so Cool Afterall
P. Bergeron, Mukremin Kilic, Simon Blouin +3
A recent analysis of the 100 pc white dwarf sample in the SDSS footprint demonstrated for the first time the existence of a well defined ultracool -- or IR-faint -- white dwarf seq…
First semi-empirical test of the white dwarf mass-radius relationship using a single white dwarf via astrometric microlensing
Peter McGill, Jay Anderson, Stefano Casertano +15
In November 2019, the nearby single, isolated DQ-type white dwarf LAWD 37 (WD 1142-645) aligned closely with a distant background source and caused an astrometric microlensing even…
Four new deeply-eclipsing white dwarfs in ZTF
Alekzander Kosakowski, M. Kilic, W. R. Brown +2
We present the results of a search for deeply-eclipsing white dwarfs in the ZTF Data Release 4. We identify nine deeply-eclipsing white dwarf candidates, four of which we followed…
On the Spectral Evolution of Hot White Dwarf Stars. III. The PG 1159DODBDQ Evolutionary Channel Revisited
A. Bédard, P. Bergeron, P. Brassard
We continue our comprehensive theoretical investigation of the spectral evolution of white dwarfs based on sophisticated simulations of element transport. In this paper, we focus o…
