Exsolution process in white dwarf stars
Maria Camisassa, Denis A. Baiko, Santiago Torres +1
White dwarf (WD) stars are considered cosmic laboratories to study the physics of dense plasma. Furthermore, the use of WD stars as cosmic clocks to date stellar populations and ma…
Main sequence companions to white dwarfs II: the age-activity-rotation relation from a sample of Gaia common proper motion pairs
A. Rebassa-Mansergas, J. Maldonado, R. Raddi +8
Magnetic activity and rotation are related to the age of low-mass main sequence stars. To further constrain these relations, we study a sample of 574 main sequence stars members of…
The unusual planetary nebula nucleus in the Galactic open cluster M37 and six further hot white dwarf candidates
Klaus Werner, Nicole Reindl, Roberto Raddi +6
Planetary nebulae in Galactic open star clusters are rare objects; only three are known to date. They are of particular interest because their distance can be determined with high…
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…
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…
An irradiated-Jupiter analogue hotter than the Sun
Na'ama Hallakoun, Dan Maoz, Alina G. Istrate +10
Planets orbiting close to hot stars experience intense extreme-ultraviolet radiation, potentially leading to atmosphere evaporation and to thermal dissociation of molecules. Howeve…
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…
Photometric follow-up of 43 new eclipsing white dwarf plus main-sequence binaries from the ZTF survey
Alex J. Brown, Steven G. Parsons, Jan van Roestel +12
Wide-field time-domain photometric sky surveys are now finding hundreds of eclipsing white dwarf plus M dwarf binaries, a population encompassing a wealth of information and potent…
