The Milky Way and the Local Group (MWLG)
  • Publication
    Uncovering the birth of the Milky Way through accurate stellar ages with Gaia
    Accurate distances to individual Milky Way stars provided by Gaia have allowed us to derive stellar age distributions from colour─magnitude diagrams (CMD)...

    Uncovering the birth of the Milky Way through accurate stellar ages with Gaia
    Knowledge of the ages of the stars formed over a galaxy's lifetime is fundamental to an understanding of its formation and evolution. However, stellar ages are...
  • Publication
    Understanding the evolution and dust formation of carbon stars in the Large Magellanic Cloud via the JWST
    Context. Carbon stars have been, and still are, extensively studied. Given their complex internal structure and their peculiar chemical composition, they are...
  • Publication
    Unveiling shocks in planetary nebulae
    The propagation of a shock wave into a medium is expected to heat the material beyond the shock, producing noticeable effects in intensity line ratios such as...
  • Publication
    Unveiling the chemical fingerprint of phosphorus-rich stars. I. In the infrared region of APOGEE-2
    Context The origin of phosphorus, one of the essential elements for life on Earth, is currently unknown. Prevalent models of Galactic chemical evolution (GCE)...
  • Publication
    Updated BaSTI Stellar Evolution Models and Isochrones. II. α-enhanced Calculations
    This is the second paper of a series devoted to presenting an updated release of the BaSTI (a Bag of Stellar Tracks and Isochrones) stellar model and isochrone...

    UV photolysis of polyynes at λ=254 nm and at λ>222 nm
    Not Available
  • Publication
    Variability of OB stars from TESS southern Sectors 1-13 and high-resolution IACOB and OWN spectroscopy
    Context. The lack of high-precision long-term continuous photometric data for large samples of stars has impeded the large-scale exploration of pulsational...

    Variable stars in Local Group Galaxies - I. Tracing the early chemical enrichment and radial gradients in the Sculptor dSph with RR Lyrae stars
    We identified and characterized the largest (536) RR Lyrae (RRL) sample in a Milky Way dSph satellite (Sculptor) based on optical photometry data collected over...
