“…The transit parameters were determined in the same manner as described in the case of CoRoT-6b (Fridlund et al 2010). The pre-processed light curve was divided by its median, and a new light curve was constructed by convolving it with a fourth order Savitzky-Golay filter (Press et al 2002).…”

We announce the discovery of the transiting planet CoRoT-13b. Ground-based follow-up in CFHT and IAC80 confirmed CoRoT's observations. The mass of the planet was measured with the HARPS spectrograph and the properties of the host star were obtained analyzing HIRES spectra from the Keck telescope. It is a hot Jupiter-like planet with an orbital period of 4.04 days, 1.3 Jupiter masses, 0.9 Jupiter radii, and a density of 2.34 g cm −3 . It orbits a G0V star with T eff = 5 945 K, M * = 1.09 M , R * = 1.01 R , solar metallicity, a lithium content of +1.45 dex, and an estimated age of between 0.12 and 3.15 Gyr. The lithium abundance of the star is consistent with its effective temperature, activity level, and age range derived from the stellar analysis. The density of the planet is extreme for its mass, implies that heavy elements are present with a mass of between about 140 and 300 M ⊕ .

“…To date it has led to the discovery of ten extrasolar planets: CoRoT-7b, the first superEarth with measured radius and mass (Léger et al 2009;Queloz et al 2008); three inflated hot Jupiters: CoRoT-1b , CoRoT-2b (Alonso et al 2008a), and CoRoT-5b (Rauer et al 2009); CoRoT-3b, "the first secure inhabitant of the brown dwarf desert" (Deleuil et al 2008); two Jupiter-like planets with an orbital period of approximately 9 days: CoRoT-4b (Aigrain et al 2008;Moutou et al 2008) and CoRoT-6b (Fridlund et al 2010); the hot sub-Saturn CoRoT-8b (Bordé et al 2010); and the long-period temperate giant planet CoRoT-9b (Deeg et al 2010). …”

Context. The space telescope CoRoT searches for transiting extrasolar planets by continuously monitoring the optical flux of thousands of stars in several fields of view. Aims. We report the discovery of CoRoT-10b, a giant planet on a highly eccentric orbit (e = 0.53 ± 0.04) revolving in 13.24 days around a faint (V = 15.22) metal-rich K1V star. Methods. We used CoRoT photometry, radial velocity observations taken with the HARPS spectrograph, and UVES spectra of the parent star to derive the orbital, stellar, and planetary parameters. Results. We derive a radius of the planet of 0.97 ± 0.07 R Jup and a mass of 2.75 ± 0.16 M Jup . The bulk density, ρ p = 3.70 ± 0.83 g cm −3 , is ∼2.8 that of Jupiter. The core of CoRoT-10b could contain up to 240 M ⊕ of heavy elements. Moving along its eccentric orbit, the planet experiences a 10.6-fold variation in insolation. Owing to the long circularisation time, τ circ > 7 Gyr, a resonant perturber is not required to excite and maintain the high eccentricity of CoRoT-10b.

“…Three more planets have previously been reported from this run: CoRoT-6b (Fridlund et al 2010), CoRoT-9b (Deeg et al 2010), and CoRoT-11b (Gandolfi et al 2010).…”

“…These spectra were analyzed to derive the effective temperature, surface gravity, and abundances of some elements. As described in Fridlund et al (2010), to that purpose we used several methods: Balmer-line fitting and the SME and VWA packages. For the surface gravity, we used the lines of Mg ib at 5184 Å and of Ca i at 6122 Å, 6162 Å and 6439 Å as diagnostics.…”

We report the discovery of two transiting exoplanets, CoRoT-25b and CoRoT-26b, both of low density, one of which is in the Saturn mass-regime. For each star, ground-based complementary observations through optical photometry and radial velocity measurements secured the planetary nature of the transiting body and allowed us to fully characterize them. For CoRoT-25b we found a planetary mass of 0.27 ± 0.04 M Jup , a radius of 1.08 +0.3 −0.10 R Jup and hence a mean density of 0.15 +0.15 −0.06 g cm −3 . The planet orbits an F9 mainsequence star in a 4.86-day period, that has a V magnitude of 15.0, solar metallicity, and an age of 4.5 +1.8 −2.0 -Gyr. CoRoT-26b orbits a slightly evolved G5 star of 9.06 ± 1.5-Gyr age in a 4.20-day period that has solar metallicity and a V magnitude of 15.8. With a mass of 0.52± 0.05 M Jup , a radius of 1.26 +0.13 −0.07 R Jup , and a mean density of 0.28 +0.09 −0.07 g cm −3 , it belongs to the low-mass hot-Jupiter population. Planetary evolution models allowed us to estimate a core mass of a few tens of Earth mass for the two planets with heavy-element mass fractions of 0.52 +0.08 −0.15 and 0.26 +0.05 −0.08 , respectively, assuming that a small fraction of the incoming flux is dissipated at the center of the planet. In addition, these models indicate that CoRoT-26b is anomalously large compared with what standard models could account for, indicating that dissipation from stellar heating could cause this size.
