Description
We model the emergence of buoyant magnetic flux from the convection zone into the photosphere by means of 3D radiative MHD simulations using the MURaM code. In a series of simulations, we study how an initially buoyant magnetic flux tube rises in the presence of granular convection. The simulations take into account the effects of radiative energy exchange, ionization effects in the equation of state and compressibility. An emphasis of this talk is the comparison of observational diagnostics from the simulations with recent observations from Hinode SOT.

    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

    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
