Scientific Analysis of CoRoT Light Curves — •Juan Cabrera — Institut für Planetenforschung - DLR - Rutherfordstr. 2 12489 Berlin

The CoRoT satellite was launched on December 2006 with two goals: the search for extrasolar planets and the study of the internal structure of stars. So far, six planets and a brown dwarf (with 20 Jupiter masses) have been reported and several results on stellar seismology have been published.

This presentation will show the treatment of the data provided by the satellite CoRoT and the different tools used to analyze the signal. A careful study of the scientific output, the light curves, provides information about the presence of planets, results about the thermal structure of the transiting planet through the analysis of the secondary eclipse, the search for multiple planetary systems through the perturbations in the ephemeris of transits, the search for reflected light of non transiting planets, the study of the stellar activity of the star, the interactions between the star and the planet and the search for moons and rings around transiting planets. Interesting results in these areas will be presented.
