Description
We report on the follow up observations after the report of ~10 mHz quasi-periodic oscillations (QPO -- ATel #3225) in the X-ray light curve of the ongoing outburst of the black hole candidate IGR J17091-3624 (ATel #3144, #3159, #3167, #3203) RXTE/PCA observations performed on March 19th and March 22nd, 2011, show a continuous progression of flare-like events which occur very regularly in a quasi-periodic manner at a rate between 25 and 30 mHz.

    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
