    Blue supergiants as a progenitor of intermediate-luminosity red transients
    The current perspective about the explosions of massive hydrogen-rich blue supergiants is that they resemble SN 1987A. These so-called peculiar Type II...

    Bolometric Treatment of Irradiation Effects: General Discussion and Application to Binary Stars
    A general framework for dealing with irradiation effects in the bolometric sense—specifically, reflection with heat absorption and the consequent redistribution...

    Boron Abundances in Early B Dwarfs of the Galactic Open Cluster NGC 3293
    New boron abundances or upper limits have been determined for eight early B stars in the young Galactic open cluster NGC 3293, using UV spectra obtained by the...

    Boron depletion in Galactic early B-type stars reveals two different main sequence star populations
    Context. The evolution and fate of massive stars are thought to be affected by rotationally induced internal mixing. The surface boron abundance is a sensitive...

    Building galaxies, stars, planets and the ingredients for life between the stars. The science behind the European Ultraviolet-Visible Observatory
    This contribution gathers the contents of the white paper submitted by the UV community to the Call issued by the European Space Agency in March 2013, for the...

    C and N abundances of main sequence and subgiant branch stars in NGC 1851
    We present the first chemical analysis of stars on the double subgiant branch (SGB) of the globular cluster NGC 1851. We obtained 48 Magellan IMACS spectra of...

    C/O ratios in planetary nebulae with dual-dust chemistry from faint optical recombination lines
    We present deep high-resolution (R ˜ 15 000) and high-quality UVES optical spectrophotometry of nine planetary nebulae with dual-dust chemistry. We compute...

    Calcium triplet metallicity calibration for stars in the Galactic bulge
    Aims: We present a new calibration of the calcium II triplet equivalent widths versus [Fe/H], constructed upon K giant stars in the Galactic bulge. This...

    Candidate LBV stars in galaxy NGC 7793 found via HST photometry + MUSE spectroscopy
    Only about 19 Galactic and 25 extragalactic bonafide luminous blue variables (LBVs) are known to date. This incomplete census prevents our understanding of this...
