Local mixing length theory with compositional effects:\ First application to asymptotic giant branch evolution
M. M. Ocampo, M. M. Miller Bertolami, A. H. Córsico +1
During the evolution of stars on the asymptotic giant branch (AGB), thermal pulses lead to the formation of strongly stratified layers in the outer regions of the CO core, which mi…
White dwarf-main sequence binaries from Gaia EDR3: the unresolved 100pc volume-limited sample
A. Rebassa-Mansergas, E. Solano, F. M. Jiménez-Esteban +6
We use the data provided by the Gaia Early Data Release 3 to search for a highly-complete volume-limited sample of unresolved binaries consisting of a white dwarf and a main sequen…
A new instability domain of CNO-flashing low-mass He-core stars on their early white-dwarf cooling branches
Leila M. Calcaferro, Alejandro H. Córsico, Leandro G. Althaus +1
Before reaching their quiescent terminal white-dwarf cooling branch, some low-mass helium-core white dwarf stellar models experience a number of nuclear flashes which greatly reduc…
The pulsational properties of ultra-massive DB white dwarfs with carbon-oxygen cores coming from single-star evolution
Alejandro H. Córsico, Leandro G. Althaus, Pilar Gil Pons +1
Ultra-massive white dwarfs are relevant for their role as type Ia Supernova progenitors, the occurrence of physical processes in the asymptotic giant-branch phase, the existence of…
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…
Pulsating hydrogen-deficient white dwarfs and pre-white dwarfs observed with TESS: I. Asteroseismology of the GW Vir stars RX J2117+3412, HS 2324+3944, NGC 6905, NGC 1501, NGC 2371, and K 1-16
Alejandro H. Córsico, Murat Uzundag, S. O. Kepler +7
In this paper, we present a detailed asteroseismological analysis of six GW Vir stars including the observations collected by the TESS mission. We processed and analyzed TESS obser…
