    Stellar seismology of gamma Dor pulsators in times of the CoRoT and Kepler satellite missions.
    Gamma Dor stars (M = 1.2-2.5 M⊙; spectral type A-F) are very interesting from an asteroseismic point of view. They show gravity modes, which are the only modes...

    Study of the planetary system HD 46375 with CoRoT and ground-based support
    At the end of 2008, on ideas of teams from the Observatoire de la Côte d’Azur (OCA) and IAC, the CoRoT satellite observed the star HD 46375, known to host a non...

    Studying galaxies at low and high redshifts with GRBs
    Long gamma-ray bursts are supposed to be connected to the death of very massive stars. Due to their brightness, we can detect them to much larger distances than...

    Studying the Halo via Its NEarby low-mass Dwarfs
    Studying the Halo via Its NEarby low-mass Dwarfs (SHINED) is an ongoing project aiming to understand the Galactic halo with metal-deficient low-mass stars (LMS)...

    Supergiant Stars as Extragalactic Probes of Cosmic Abundances and Distances
    The determination of chemical composition and distances of galaxies is crucial for constraining the theory of galaxy formation and evolution in a dark energy...

    Supergiants with an Interesting Past
    Exciting things may have happened sometimes to the stars we see in the sky today. For example, Betelgeuse, also known as Alpha-Ori, an M-type red supergiant...

    Testing stellar evolutionary models from detached eclipsing binary stars
    We employ a Bayesian method to infer stellar parameters from the PARSEC v1.2S library of stellar evolution models and test the accuracy of these theoretical...

    Testing stellar evolutionary theory with asteroseismology and/in binary stars
    The theory of stellar evolution is well developed over the past decades, and in particular the predictions of one dimensional numerical models have passed basic...

    The binary population in Galactic globular clusters: theory versus observations
    I present the first results of a long term project devoted to the study of the evolution of the binary population in globular clusters. Using deep ACS@HST...
