Description
Context: The pioneer space mission for photometric planet searches,
CoRoT, steadily monitors about 12 000 stars in each of its fields of
view. Transit candidates can be detected early in the processing of the
data and before the end of a run of observation. Aims: We report
the detection of the first planet discovered by CoRoT and characterizing
it with the help of follow-up observations. Methods: Raw data
were filtered from outliers and residuals at the orbital period of the
satellite. The orbital parameters and the radius of the planet were
estimated by best fitting the phase folded light curve with 34
successive transits. Doppler measurements with the SOPHIE spectrograph
permitted us to secure the detection against binaries and to estimate
the mass of the planet. Results: The accuracy of the data is very
high with a dispersion in the 2.17 min binned phase-folded light curve
that does not exceed ~3.×10-4 in flux unit. The planet
orbits a mildly metal-poor G0V star of magnitude V=13.6 in 1.5 days. The
estimated mass and radius of the star are 0.95±0.15
M&sun; and 1.11±0.05 R&sun;. We find the
planet has a radius of 1.49±0.08 R_Jup, a mass of
1.03±0.12 M_Jup, and a particularly low mean density of
0.38±0.05 g cm-3.
The CoRoT space mission, launched on Dec. 27th, 2006, was developed and
is operated by the CNES, with participation of the Science Program of
ESA, ESTEC/RSSD, Austria, Belgium, Brazil, Germany and Spain. Based in
part on observations with the SOPHIE spectrograph at Obs. de Haute
Provence, France. Table [see full text] is only available in electronic

The principal objectives of this project are: 1) to study the structure and dynamics of the solar interior, 2) to extend this study to other stars, 3) to search for extrasolar planets using photometric methods (primarily by transits of their host stars) and their characterization (using radial velocity information) and 4) the study of the planetary
