  • 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...

    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
    Unveiling the chemical fingerprint of phosphorus-rich stars: II. Heavy-element abundances from UVES/VLT spectra
    Context. The atmospheres of phosphorus-rich (P-rich) stars have been shown to contain between 10 and 100 times more P than our Sun. Given its crucial role as an...
  • Publication
    Unveiling the purely young star formation history of the SMC's northeastern shell from colour-magnitude diagram fitting
    We obtain a quantitative star formation history (SFH) of a shell-like structure ('shell') located in the northeastern part of the Small Magellanic Cloud (SMC)...
  • 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...

    Variability of Central Stars of Planetary Nebulae with the Zwicky Transient Facility. II. Long-timescale Variables including Wide Binary and Late Thermal Pulse Candidates
    In this second paper on our variability survey of central stars of planetary nebulae (CSPNe) using the Zwicky Transient Facility (ZTF), we report 11 long...
  • 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...
