White dwarf Random Forest classification through Gaia spectral coefficients
Enrique Miguel García-Zamora, Santiago Torres, Alberto Rebassa-Mansergas
The third data release of Gaia has provided approximately 220 million low resolution spectra. Among these, about 100,000 correspond to white dwarfs. The magnitude of this quantity…
White dwarf spectral type-temperature distribution from Gaia-DR3 and the Virtual Observatory
S. Torres, P. Cruz, R. Murillo-Ojeda +6
The characterization of white dwarf atmospheres is crucial for accurately deriving stellar parameters such as effective temperature, mass, and age. We aim to classify the populatio…
General relativistic pulsations of ultra-massive ZZ Ceti stars
Alejandro H. Córsico, S. Reece Boston, Leandro G. Althaus +4
Ultra-massive white dwarf stars are currently being discovered at a considerable rate, thanks to surveys such as the {\it Gaia} space mission. These dense and compact stellar remna…
Carbon-oxygen ultra-massive white dwarfs in general relativity
Leandro G. Althaus, Alejandro H. Córsico, María E. Camisassa +4
We employ the La Plata stellar evolution code, LPCODE, to compute the first set of constant rest-mass carbon-oxygen ultra-massive white dwarf evolutionary sequences for masses high…
A hidden population of white dwarfs with atmospheric carbon traces in the Gaia bifurcation
Maria Camisassa, Santiago Torres, Mark Hollands +4
The ESA Gaia space mission has revealed a bifurcation of the white dwarf (WD) sequence on the color magnitude diagram in two branches: A and B. While the A branch consists mostly o…
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…
