Description
A method is presented for reconstructing the intensity profile, I, formed in the magnetic elements which have diameters smaller than the best presently achievable spatial resolution. It follows the same line as in Solanki and Stenflo (1984). As a starting point I and V of the facula and the I observed in the quiet sun are used. The filling factor, and the ratio between the continuum intensity of the magnetic and nonmagnetic parts of the photosphere can be obtained indirectly. For that purpose only the Unno equations, a triplet Zeeman pattern, a longitudinal magnetic field and a two-component model are needed. The method has been applied to some Fourier transform spectrometer data with promising results. As the absolute continuum intensities are unkown, rendering inaccurate the evaluation of the filling factor and the continuum contrast, only the normalized I profile is obtained.

    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
