Aims: The CoRoT space mission continues to photometrically monitor about 12 000 stars in its field-of-view for a series of target fields to search for transiting extrasolar planets ever since 2007. Deep transit signals can be detected quickly in the ldquoalarm-moderdquo in parallel to the ongoing target field monitoring. CoRoT's first planets have been detected in this mode.
Methods: The CoRoT raw lightcurves are filtered for orbital residuals, outliers, and low-frequency stellar signals. The phase folded lightcurve is used to fit the transit signal and derive the main planetary parameters. Radial velocity follow-up observations were initiated to secure the detection and to derive the planet mass.
Results: We report the detection of CoRoT-5b, detected during observations of the LRa01 field, the first long-duration field in the galactic anti-center direction. CoRoT-5b is a ldquohot Jupiter-typerdquo planet with a radius of 1.388$^+0.046$$_-0.047$ RJup, a mass of 0.467$^+0.047$$_-0.024$ MJup, and therefore, a mean density of 0.217$^+0.031$$_-0.025$ g cm$^-3$. The planet orbits an F9V star of 14.0 mag in 4.0378962 plusmn 0.0000019 days at an orbital distance of 0.04947$^+0.00026$$_-0.00029$ AU. Observations made with SOPHIE spectrograph at the Observatoire de Haute Provence (07B.PNP.MOUT), France, and HARPS spectrograph at ESO La Silla Observatory (072.C-0488(E), 082.C-0312(A)), and partly based on observations made at the Anglo-Australian Telescope. The CoRoT space mission, launched on December 27, 2006, was developed and is operated by CNES, with the contribution of Austria, Belgium, Brasil, ESA, Germany, and Spain.
