An evolutionary channel for CO-rich and pulsating He-rich subdwarfs
Marcelo M. Miller Bertolami, Tiara Battich, Alejandro H. Córsico +2
Recently a new class of hot subluminous stars strongly enriched in C and O have been discovered (CO-sdOs). These stars show abundances very similar to those observed in PG1159 star…
On the evolution of ultra-massive white dwarfs
María E. Camisassa, Leandro G. Althaus, Alejandro H. Córsico +6
Ultra-massive white dwarfs are powerful tools to study various physical processes in the Asymptotic Giant Branch (AGB), type Ia supernova explosions and the theory of crystallizati…
Pulsation properties of ultra-massive DA white dwarf stars with ONe cores
Francisco C. De Gerónimo, Alejandro H. Córsico, Leandro G. Althaus +2
Ultra-massive DA WD stars are expected to harbor ONe cores resulting from the progenitor evolution through the Super-AGB phase. As evolution proceeds during the WD cooling phase, a…
