Description
We present preliminary results of the kinematics of HII regions and diffuse gas in the irregular galaxies IC10 and NGC 4449. From Fabry-Perot Hα and [SII] observations, we have measured the radial velocities and velocity dispersions of the HII regions in these galaxies and compared them with a similar analysis done in the Small Magellanic Cloud. We study the interactions between massive stars and the interstellar medium in these galaxies via winds and supernovae. In order to do this, we have identified regions with enhanced [SII]/Hα emission, that are SNR candidates.

    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
