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…
Asteroseismic signatures of the helium-core flash
Marcelo M. Miller Bertolami, Tiara Battich, Alejandro H. Corsico +2
All evolved stars with masses undergo a helium(He)-core flash at the end of their first stage as a giant star. Although theoretically predicted more than…
On the formation of hydrogen-deficient low-mass white dwarfs
Tiara Battich, Leandro G. Althaus, Alejandro H. Córsico
Two of the possibilities for the formation of low-mass () hydrogen-deficient white dwarfs are the occurrence of a very-late thermal pulse after th…
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…
A quantitative NLTE analysis of visual and ultraviolet spectra of four helium-rich subdwarf O stars
Markus Schindewolf, Peter Nemeth, Ulrich Heber +4
Hot subdwarfs represent a poorly understood late phase of stellar evolution. While binary evolution plays an important role for B-subdwarfs (sdB), the origin of the He dominated O-…
