Description
Abundances of oxygen in two ultra-metal-poor giants have been derived from measurements of the oxygen triplet at 7771-5Å in the near-IR performed in high-resolution and high S/N ratio spectra obtained with KeckI/HIRES. A detailed non-LTE analysis of Fe lines has been carried out for our targets providing more reliable stellar parameters and metallicities.

    Convection, rotation, and magnetic activity of solar-like stars from asteroseismology
    During the last decade, our understanding of stellar physics and evolution has undergone a tremendous revolution thanks to asteroseismology. Space missions such as CoRoT, Kepler, K2, and TESS have already been observing millions of stars providing high-precision photometric data. With these data, it is possible to study the convection of stars

    Tales of stellar & binary co-evolution, told by stellar oscillations
    Stellar binarity and stellar oscillations are mostly seen and studied as two separate phenomena. Sometimes, one process is even complicating the analysis of the other beyond the liking of one or the other research community. However, the complete picture painted by the physical constraints provided by the combination of both processes represents a
