Abstract: The COROT (COnvection, ROtation and planetary
Transits) mission, very successfully launched in December 2006, is
intended to provide high-precision (noise level in the frequency
spectrum 0.7 ppm over a 5 d time baseline) photometric
monitoring of stellar targets to achieve three main objectives:
1) stellar seismology of dwarf stars to give direct information on
the structure and dynamics of their interiors (Seismology programme).
Among those, a few bright stars (V<8.0) will be studied continuously
for 150 days (primary targets), along with up to 9 fainter stars
(V<9.5, secondary targets), located in the same field of the
primary targets;
2) the detection of Earth-like planets from eclipses of their parent
stars (Exoplanet programme);
3) the accurate high precision, continuous, photometric monitoring
of many thousands of fainter stars that lie aside in the Exoplanetary
fields.
