Comparison of methods used to derive the Galactic star formation history from white dwarf samples
Emily K. Roberts, Pier-Emmanuel Tremblay, Mairi W. O'Brien +4
We compare three methods of deriving the local Galactic star formation history, using as a benchmark the Gaia-defined 40 pc white dwarf sample, currently the largest volume complet…
The prototype double-faced white dwarf has a thin hydrogen layer across its entire surface
Antoine Bédard, Pier-Emmanuel Tremblay
Some white dwarfs undergo significant changes in atmospheric composition owing to the diffusion and mixing of residual hydrogen in a helium-rich envelope. Of particular interest ar…
Long-lived Habitable Zones around White Dwarfs undergoing Neon-22 Distillation
Andrew Vanderburg, Antoine Bédard, Juliette C. Becker +1
White dwarf stars have attracted considerable attention in the past 15 years as hosts for potentially habitable planets, but their low luminosity and continuous cooling are major c…
The photospheres of the hottest fastest stars in the Galaxy
Klaus Werner, Nicole Reindl, Thomas Rauch +2
We perform nonlocal thermodynamic equilibrium (NLTE) model atmosphere analyses of the three hottest hypervelocity stars (space velocities between 1500-2800 km s) k…
Measurements of Physical Parameters of White Dwarfs: A Test of the Mass-Radius Relation
Antoine Bédard, Pierre Bergeron, Gilles Fontaine
We present a detailed spectroscopic and photometric analysis of 219 DA and DB white dwarfs for which trigonometric parallax measurements are available. Our aim is to compare the ph…
