    The Cool Supergiant Population of the Massive Young Star Cluster RSGC1
    We present new high-resolution near-IR spectroscopy and OH maser observations to investigate the population of cool luminous stars of the young massive Galactic...

    The Correlation between Mixing Length and Metallicity on the Giant Branch: Implications for Ages in the Gaia Era
    In the updated APOGEE-Kepler catalog, we have asteroseismic and spectroscopic data for over 3000 first ascent red giants. Given the size and accuracy of this...

    The Counterjet of HH 30: New Light on Its Binary Driving Source
    We present new [S II] images of the Herbig-Haro (HH) 30 jet and counterjet observed in 2006, 2007, and 2010 that, combined with previous data, allowed us to...

    The Disc-Halo Structure of NGC 3109
    We present the results of V and I photometries for ~56,500 stars of NGC 3109 obtained from a 467.26(')2 wide-field observations. The internal extinction does...

    The distance to the C component of I Zw 18 and its star formation history. A probabilistic approach
    Aims: We analyzed the resolved stellar population of the C component of the extremely metal-poor dwarf galaxy I Zw18 in order to evaluate its distance and star...

    The Distance, Mass, and Radius of the Neutron Star in 4U 1608-52
    Low-mass X-ray binaries (LMXBs) that show thermonuclear bursts are ideal sources for constraining the equation of state of neutron star matter. The lack of...

    The Double Dust Envelopes of R Coronae Borealis Stars
    The study of extended, cold dust envelopes surrounding R Coronae Borealis (RCB) stars began with their discovery by the Infrared Astronomical Satellite. RCB...

    The double sub-giant branch of NGC 6656 (M 22): a chemical characterization
    We present an abundance analysis of 101 subgiant branch (SGB) stars in the globular cluster M 22. Using low-resolution FLAMES/GIRAFFE spectra we have determined...

    The early days of the Sculptor dwarf spheroidal galaxy
    We present the high-resolution spectroscopic study of five -3.9 ≤ [Fe/H] ≤ -2.5 stars in the Local Group dwarf spheroidal, Sculptor, thereby doubling the number...
