    The 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)...

    The 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...

    The 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...

    The 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...

    Time-resolved photometry of BN and CU Cancri, two delta Scuti stars in the Praesepe cluster. Fourth photometry campaign of the STEPHI network
    The fourth photometry campaign of the Stellar photometry International (STEPHI) network was carried out in January 1992. On this occasion, the delta Scuti-like...

    Ultraviolet and infrared monitoring of FG Sagittae during 1982-1989 - Evolutionary status
    Ultraviolet IUE spectra and infrared JHKL photometry of FG Sge obtained over the period 1982-1989 indicate that the cooling rate of the star observed until...

    Very 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...

    Violent star formation in NGC 2363
    We present narrowband H-alpha imaging and long-slit optical and near-infrared spectroscopy of the giant H II region NGC 2363. The spectroscopic data are taken...
