Descripción
DQ white dwarfs have Teff values below 13000 K and are characterized by the presence of trace amounts of carbon in their helium-rich atmospheres. The wide range of surface carbon abundances they exhibit could be reflecting the existence of hydrogen-deficient white dwarfs with a variety of evolutionary history and formation processes. The aim of this work is to analize distinct evolutionary channels that could lead to the formation of DQ white dwarfs.

    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
