    Luminosity and mass functions of the three main sequences of the globular cluster NGC 2808
    High-precision HST photometry has revealed that the globular cluster (GC) NGC 2808 hosts a triple main sequence (MS) corresponding to three stellar populations...

    Luminosity-colour relations for red clump stars
    We calibrated the absolute magnitudes M V , M J , M_{Ks} and M g of red clump stars in terms of colours. M V and M g are strongly dependent on colour, while the...

    Luminosity-colour relations for thin-disc main-sequence stars
    In this study we present the absolute magnitude calibrations of thin-disc main-sequence stars in the optical , and in the near-infrared . Thin-disc stars are...

    M1-78: a nitrogen-rich Galactic compact H II region beyond the Perseus arm
    Context: There is considerable controversy surrounding the nature of M1-78, a compact nebula located beyond the Perseus arm. It was first classified as a...

    Machine learning for galactic archaeology: a chemistry-based neural network method for identification of accreted disc stars
    We develop a method ('Galactic Archaeology Neural Network', GANN) based on neural network models (NNMs) to identify accreted stars in galactic discs by only...

    Magnesium isotopes: a tool to understand self-enrichment in globular clusters
    A critical issue in the asymptotic giant branch (AGB) self-enrichment scenario for the formation of multiple populations in globular clusters (GCs) is the...

    Mapping the core of the Tarantula Nebula with VLT-MUSE. I. Spectral and nebular content around R136
    We introduce VLT-MUSE observations of the central 2'× 2' (30 × 30 pc) of the Tarantula Nebula in the Large Magellanic Cloud. The observations provide an...

    Mapping the core of the Tarantula Nebula with VLT-MUSE. II. The spectroscopic Hertzsprung-Russell diagram of OB stars in NGC 2070
    We present the spectroscopic analysis of 333 OB-type stars extracted from VLT-MUSE observations of the central 30 × 30 pc of NGC 2070 in the Tarantula Nebula on...

    Mapping the Galactic disc with the LAMOST and Gaia red clump sample: II. 3D asymmetrical kinematics of mono-age populations in the disc between 6-14 kpc
    We perform analysis of the 3D kinematics of Milky Way disc stars in mono-age populations. We focus on stars between Galactocentric distances of R = 6 and 14 kpc...
