    A new visual - near-infrared diagnostic to estimate the metallicity of cluster and field dwarf stars
    We present a theoretical calibration of a new metallicity diagnostic based on the Strömgren index m1 and on visual - near-infrared (NIR) colors to estimate the...

    A peculiar Of star in the Local Group galaxy IC 1613
    Context. Results from the theory of radiatively driven winds are nowadays incorporated in stellar evolutionary and population synthesis models, and are used in...

    A photometric redshift of z = 1.8{+0.4}{-0.3} for the AGILE GRB 080514B
    The AGILE gamma-ray burst GRB 080514B is the first detected to have emission above 30 MeV and an optical afterglow. However, no spectroscopic redshift for this...

    A photometric study of globular clusters observed by the APOGEE survey
    In this paper, we describe the photometric and spectroscopic properties of multiple populations in seven northern globular clusters. In this study, we employ...

    A Photometric Study of the Outer Halo Globular Cluster NGC 5824
    Multi-wavelength CCD photometry over 21 years has been used to produce deep color–magnitude diagrams (CMDs) together with light curves for the variables in the...
  • Publication
    A plague of magnetic spots among the hot stars of globular clusters
    For more than six decades, the quest to understand the formation of hot (about 20,000-30,000 K) extreme horizontal branch (EHB) stars in Galactic globular...

    A primitive stellar structure helps us to unravel the earliest phases of the Milky Way
    Just as archaeology examines the ground with great care to find valuable objects which helps us to get to know ancient civilizations, astronomers look at the...

    A probabilistic deep learning model to distinguish cusps and cores in dwarf galaxies
    Numerical simulations within a cold dark matter (DM) cosmology form haloes whose density profiles have a steep inner slope ('cusp'), yet observations of...

    A search for diffuse bands in fullerene planetary nebulae: evidence of diffuse circumstellar bands
    Large fullerenes and fullerene-based molecules have been proposed as carriers of diffuse interstellar bands (DIBs). The recent detection of the most common...
