Description
We propose the use of the break in the HII region luminosity function (LF) as a possible refined powerful standard candle for extragalactic distances. The invariance and high luminosity of the LF break has been proposed in previous studies as a possible secondary standard candle, but it is calibrated here for the first time using the LFs of NGC 925 and M 100, whose Cepheid distances have been determined in the HST Extragalactic Distance Scale Key Project.

    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
