Magnetic activity in the photosphere of CoRoT-Exo-2a. Active longitudes and short-term spot cycle in a young Sun-like star
A. F. Lanza, I. Pagano, G. Leto +18
The space experiment CoRoT has recently detected transits by a hot Jupiter across the disc of an active G7V star (CoRoT-Exo-2a) that can be considered as a good proxy for the Sun a…
CoRoT and stellar activity: preliminary results from the modelling of CoRoT-Exo-2a
A. F. Lanza, I. Pagano, G. Leto +3
We present a preliminary analysis of the photospheric activity of CoRoT-Exo-2a, a young G7V star accompanied by a transiting hot Jupiter recently discovered by CoRoT. We apply spot…
First time-series optical photometry from Antarctica
K. G. Strassmeier, R. Briguglio, T. Granzer +11
Beating the Earth's day-night cycle is mandatory for long and continuous time-series photometry and had been achieved with either large ground-based networks of observatories at di…
RACE-OC Project: Rotation and variability in the open cluster NGC2099 (M37)
S. Messina, E. Distefano, Padmakar Parihar +4
Rotation and solar-type magnetic activity are closely related to each other in stars of G or later spectral types. Presence and level of magnetic activity depend on star's rotation…
