SOPHIE+: First results of an octagonal-section fiber for high-precision radial velocity measurements
F. Bouchy, R. F. Diaz, G. Hébrard +5
High-precision spectrographs play a key role in exoplanet searches and Doppler asteroseismology using the radial velocity technique. The 1 m/s level of precision requires very high…
SOPHIE velocimetry of Kepler transit candidates VI. An additional companion in the KOI-13 system
A. Santerne, C. Moutou, S. C. C. Barros +7
We report the discovery of a new stellar companion in the KOI-13 system. KOI-13 is composed by two fast-rotating A-type stars of similar magnitude. One of these two stars hosts a t…
SOPHIE velocimetry of Kepler transit candidates VII. A false-positive rate of 35% for Kepler close-in giant exoplanet candidates
A. Santerne, R. F. Díaz, C. Moutou +6
The false-positive probability (FPP) of Kepler transiting candidates is a key value for statistical studies of candidate properties. A previous investigation of the stellar populat…
The SOPHIE search for northern extrasolar planets. V. Follow-up of ELODIE candidates: Jupiter-analogs around Sun-like stars
I. Boisse, F. Pepe, C. Perrier +21
We present radial-velocity measurements obtained in a programs underway to search for extrasolar planets with the spectrograph SOPHIE at the 1.93-m telescope of the Haute-Provence…
Transiting exoplanets from the CoRoT space mission XXI. CoRoT-19b: A low density planet orbiting an old inactive F9V-star
E. W. Guenther, R. F. Diaz, J. -C. Gazzano +51
Observations of transiting extrasolar planets are of key importance to our understanding of planets because their mass, radius, and mass density can be determined. The CoRoT space…
