Non-local thermodynamic equilibrium spectral analysis of five hot, hydrogen-deficient pre-white dwarfs
Klaus Werner, Nicole Reindl, Matti Dorsch +3
Hot, compact, hydrogen-deficient pre-white dwarfs (pre-WDs) with effective temperatures of Teff > 70,000 K and a surface gravity of 5.0 < log g < 7.0 are rather rare objects despit…
Kinematic properties of white dwarfs. Galactic orbital parameters and age-velocity dispersion relation
R. Raddi, S. Torres, A. Rebassa-Mansergas +9
We present the first detailed 3D kinematic analysis of a sample of 3133 white dwarfs that use Gaia astrometry plus radial velocities, which were measured either by Gaia or by groun…
Constraining the solar neighbourhood age-metallicity relation from white dwarf-main sequence binaries
A. Rebassa-Mansergas, J. Maldonado, R. Raddi +11
The age-metallicity relation is a fundamental tool for constraining the chemical evolution of the Galactic disc. In this work we analyse the observational properties of this relati…
8.9-hr Rotation in the Partly Burnt Runaway Stellar Remnant LP 40-365 (GD 492)
J. J. Hermes, Odelia Putterman, Mark A. Hollands +5
We report the detection of 8.914-hr variability in both optical and ultraviolet light curves of LP 40-365 (also known as GD 492), the prototype for a class of partly burnt runaway…
Towards a volumetric census of close white dwarf binaries I.Reference samples
K. Inight, B. T. Gaensicke, E. Breedt +3
Close white dwarf binaries play an important role across a range of astrophysics, including thermonuclear supernovae, the Galactic low-frequency gravitational wave signal, and the…
Blue extreme disk-runaway stars with Gaia EDR3
Andreas Irrgang, Markus Dimpel, Ulrich Heber +1
Since the discovery of hypervelocity stars in 2005, it has been widely believed that only the disruption of a binary system by a supermassive black hole at the Galactic center (GC)…
The Gaia DR2 halo white dwarf population: the luminosity function, mass distribution and its star formation history
Santiago Torres, Alberto Rebassa-Mansergas, María E. Camisassa +1
We analyze the volume-limited nearly complete 100 pc sample of 95 halo white dwarf candidates identified by the second data release of Gaia. Based on a detailed population synthesi…
