Magnetic activity in the photosphere of CoRoT-Exo-2a: Active longitudes and short-term spot cycle in a young Sun-like star

Context. The space experiment CoRoT has recently detected transits by a hot Jupiter across the disc of an active G7V star (CoRoTExo-2a) that can be considered as a good proxy for the Sun at an age of approximately 0.5 Gyr. Aims. We present a spot modelling of the optical variability of the star duri...
