PublicaciónThe Pre-He White Dwarf in the Post-mass Transfer Binary EL CVn
EL CVn is the prototype of a class of eclipsing binaries that consist of an A- or F-type main-sequence star and a hot, low-mass, pre-He white dwarf (pre-He WD)...

CharlaThe rotation of massive stars with and without compact companions
Massive stars are generally fast rotators, however, with significant dispersion. We discuss the hypothesis that all OB stars are all born with very similar...

CharlaThe shady side of Stellar modelling and its grisly impact on Asteroseismology and Galactic Archeology
Since the second half of last century, stellar evolution theory has allowed to understand the Color Magnitude Diagram of galactic star clusters, so that now we...

PublicaciónThe spectra of late-type dwarfs and sub-dwarfs in the near ultraviolet. I - Line identifications
Spectra from IUE of 6 main sequence and near main sequence stars from classes A5 to G8, between 2700 A and 2900 A wavelength are described. In toto, some 250...

PublicaciónVery Massive Stars in the local Universe
Recent studies have claimed the existence of very massive stars (VMS) up to 300 M ⊙ in the local Universe. As this finding may represent a paradigm shift for...
