Spectral classification of the 100 pc white dwarf population from Gaia-DR3 and the Virtual Observatory
F. M. Jiménez-Esteban, S. Torres, A. Rebassa-Mansergas +5
The third data release of Gaia has provided low resolution spectra for ~100,000 white dwarfs (WDs) that, together with the excellent photometry and astrometry, represent an unrival…
The evolution of ultra-massive carbon oxygen white dwarfs
María E. Camisassa, Leandro G. Althaus, Detlev Koester +3
Ultra-massive white dwarfs () are considered powerful tools to study type Ia supernovae explosions, merger events, the occurrence of physical p…
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…
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…
The formation of ultra-massive carbon-oxygen core white dwarfs and their evolutionary and pulsational properties
Leandro G. Althaus, Pilar Gil Pons, Alejandro H. Córsico +6
(Abridged abstract) We explore the formation of ultra-massive (M_{\rm WD} \gtrsim 1.05 M_\sun$), carbon-oxygen core white dwarfs resulting from single stellar evolution. We also st…
An ultra-massive white dwarf with a mixed hydrogen-carbon atmosphere as a likely merger remnant
Mark A. Hollands, Pier-Emmanuel Tremblay, Boris T. Gänsicke +11
White dwarfs are dense, cooling stellar embers consisting mostly of carbon and oxygen, or oxygen and neon (with a few percent carbon) at higher initial stellar masses. These stella…
