    The colliding-wind binary HD 168112
    Context. Radio surveys of early-type stars have revealed a number of non-thermal emitters. Most of these have been shown to be binaries, where the collision...

    The complex structure of HH 110 as revealed from Integral Field Spectroscopy
    HH 110 is a rather peculiar HerbigHaro object in Orion that originates due to the deflection of another jet (HH 270) by a dense molecular clump, instead of...

    The computation of interstellar extinction in photoionized nebulae
    Context. The proper plasma analysis practice (PPAP) method has been proposed to analyze spectroscopic data of ionized nebulae. The method is based on a coherent...

    The contribution of N-rich stars to the Galactic stellar halo using APOGEE red giants
    The contribution of dissolved globular clusters (GCs) to the stellar content of the Galactic halo is a key constraint on models for GC formation and destruction...

    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...
