Microvariability and Oscillations os STars

Detection and characterisation of: (1) acoustic oscillations in Sun-like stars, including very old stars (metal-poor subdwarfs) and magnetic stars (roAp), to probe seismically their structures and ages; (2) reflected light from giant exoplanets closely orbiting Sun-like stars, to reveal their sizes and atmospheric compositions; and (3) turbulent variations in massive evolved (Wolf-Rayet) stars to understand how they add gas to the interstellar medium.
