Transiting exoplanets from the CoRoT space mission VIII. CoRoT-7b: the first Super-Earth with measured radius
Aims. We report the discovery of very shallow (ΔF/F ≈ 3.4× 10 −4 ), periodic dips in the light curve of an active V = 11.7 G9V star observed by the CoRoT satellite, which we interpret as caused by a
The CoRoT-7 planetary system: two orbiting super-Earths
We report on an intensive observational campaign carried out with HARPS at the 3.6 m telescope at La Silla on the star CoRoT-7. Additional simultaneous photometric measurements carried out with the
Transiting exoplanets from the CoRoT space mission. II. CoRoT-Exo-2b: a transiting planet around an
Context. The CoRoT mission, a pioneer in exoplanet searches from space, has completed its first 150 days of continuous observations of ∼12 000 stars in the galactic plane. An analysis of the raw data
Magnetic activity in the photosphere of CoRoT-Exo-2a. Active longitudes and short-term spot cycle in
Context. The space experiment CoRoT has recently detected transits by a hot Jupiter across the disk of an active G7V star (CoRoTExo-2a) that can be considered as a good proxy for the Sun at an age of
Transiting exoplanets from the CoRoT space mission. I. CoRoT-Exo-1b: a low-density short-period plan
Context. The pioneer space mission for photometric planet searches, CoRoT, steadily monitors about 12,000 stars in each of its fields of view; it is able to detect transit candidates early in the
COROT: A minisat for pionnier science, asteroseismology and planets finding
Abstract COROT belongs to the minisat program of the french space agency CNES. It has two main scientific programmes: asteroseismology and search for extrasolar planets. The main characteristics of
Asymptotic and measured large frequency separations
Context. With the space-borne missions CoRoT and Kepler, a large amount of asteroseismic data is now available and has led to a variety of work. So-called global oscillation parameters are inferred
CSI 2264: Simultaneous optical and infrared light curves of young disk-bearing stars in NGC 2264 with CoRoT and Spitzer-- evidence for multiple origins of variability
We present the Coordinated Synoptic Investigation of NGC 2264, a continuous 30 day multi-wavelength photometric monitoring campaign on more than 1000 young cluster members using 16 telescopes. The
Transiting exoplanets from the CoRoT space mission: III. The spectroscopic transit of CoRoT-Exo-2b with SOPHIE and HARPS
We report on the spectroscopic transit of the massive hot-Jupiter CoRoT-Exo-2b observed with the high-precision spectrographs SOPHIE and HARPS. By modeling the radial velocity anomaly occurring
