Descripción
We present observational evidence of high-temperature spiral structure on the accretion disk of the dwarf nova IP Peg during outburst. The Doppler tomogram of ionized helium He II 4686 shows a two-arm spiral pattern on the disk image. The spiral shocks are generated by the tides raised by the secondary star on the disk and shows that a new mechanism may be important in transporting angular momentum out of the disk in addition to viscosity.

    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
