Description
Selecting stars with previously measured or estimated rotational periods the authors measured Li equivalent widths in 8 stars of the Hyades late main sequence. Plotting log N(Li) against Rossby number the authors can separate the effects of temperature and rotation. They find for stars later than F8 increased depletion with longer period, at constant surface temperature. The authors give a tentative view of the implications of these results for stellar modelling.

    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
