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…
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…
