The SOPHIE search for northern extrasolar planets. IV. Massive companions in the planet-brown dwarf boundary
R. F. Díaz, A. Santerne, J. Sahlmann +20
The mass domain where massive extrasolar planets and brown dwarfs lay is still poorly understood. Indeed, not even a clear dividing line between massive planets and brown dwarfs ha…
Corrigendum to "The upper atmosphere of the exoplanet HD209458b revealed by the sodium D lines: Temperature-pressure profile, ionization layer and thermosphere" [2011, A&A, 527, A110]
A. Vidal-Madjar, C. M. Huitson, A. Lecavelier des Etangs +7
An error was detected in the code used for the analysis of the HD209458b sodium profile (Vidal-Madjar et al. 2011). Here we present an updated T-P profile and briefly discuss the c…
Higher-precision radial velocity measurements with the SOPHIE spectrograph using octagonal-section fibers
S. Perruchot, F. Bouchy, B. Chazelas +12
High-precision spectrographs play a key role in exoplanet searches using the radial velocity technique. But at the accuracy level of 1 m.s-1, required for super-Earth characterizat…
Deriving the radial-velocity variations induced by stellar activity from high-precision photometry - Test on HD189733 with simultaneous MOST/SOPHIE data
A. F. Lanza, I. Boisse, F. Bouchy +2
Stellar activity induces apparent radial velocity (RV) variations in late-type main-sequence stars that may hamper the detection of low-mass planets and the measurement of their ma…
Spin-orbit inclinations of the exoplanetary systems HAT-P-8, HAT-P-9, HAT-P-16 and HAT-P-23
Claire Moutou, Rodrigo F. Diaz, Stephane Udry +22
We report the measurement of the spin-orbit angle of the extra-solar planets HAT-P-8 b, HAT-P-9 b, HAT-P-16 b and HAT-P-23 b, thanks to spectroscopic observations performed at the…
WASP-23b: a transiting hot Jupiter around a K dwarf and its Rossiter-McLaughlin effect
Amaury H. M. J. Triaud, Didier Queloz, Coel Hellier +17
We report the discovery of a new transiting planet in the Southern Hemisphere. It has been found by the WASP-south transit survey and confirmed photometrically and spectroscopicall…
