The composition of massive white dwarfs and their dependence on the C-burning modeling
Francisco C. De Gerónimo, Marcelo M. Miller Bertolami, Francisco Plaza +1
Recent computations of the interior composition of ultra-massive white dwarfs (WD) have suggested that some white dwarfs could be composed of neon (Ne)-dominated cores. This result…
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…
Asteroseismological analysis of the ultra-massive ZZ Ceti stars BPM~37093, GD~518, and SDSS~J0840+5222
Alejandro H. Córsico, Francisco C. De Gerónimo, María E. Camisassa +1
Ultra-massive hydrogen-rich (DA) white dwarfs (WD) are expected to have a substantial portion of their cores in a crystalline state at the effective temperatures characterizing the…
On the recent parametric determination of an asteroseismological model for the DBV star KIC 08626021
Francisco C. De Gerónimo, Tiara Battich, Marcelo M. Miller Bertolami +2
Asteroseismology of white dwarf (WD) stars is a powerful tool that allows to reveal the hidden chemical structure of WD and infer details about their evolution by comparing the obs…
The impact of pre-white dwarf evolution on the pulsational properties and asteroseismological inferences of ZZ Ceti stars
F. C. De Gerónimo, L. G. Althaus, A. H. Córsico +2
ZZ Ceti stars are pulsating white dwarfs with a carbon-oxygen core (or possibly ONe for the most massive stars) build up during the core helium burning (CHeB) and thermally pulsing…
Evolutionary and pulsational properties of ultra-massive white dwarfs. The role of oxygen-neon phase separation
F. C. De Gerónimo, M. E. Camisassa, A. H. Córsico +1
Ultra-massive hydrogen-rich white dwarfs (WDs) stars are expected to harbor oxygen/neon cores resulting from semi-degenerate carbon burning when the progenitor star evolves through…
