CharlaStars at the Eddington limit
It is often assumed that when stars reach their Eddington limit, strong outflows are initiated, and that this happens only for extreme stellar masses. I will...

CharlaStellar Rotation in the Gaia Era: Gyrochronology Under Inspection
Rotation plays an important role in the life of stars and offers a potential diagnostic to infer their ages and that of their planets. This idea is known as...

CharlaStellar seismology of gamma Dor pulsators in times of the CoRoT and Kepler satellite missions.
Gamma Dor stars (M = 1.2-2.5 M⊙; spectral type A-F) are very interesting from an asteroseismic point of view. They show gravity modes, which are the only modes...

CharlaStudy of the planetary system HD 46375 with CoRoT and ground-based support
At the end of 2008, on ideas of teams from the Observatoire de la Côte d’Azur (OCA) and IAC, the CoRoT satellite observed the star HD 46375, known to host a non...
