The spin-orbit alignment of the transiting exoplanet WASP-3b from Rossiter-McLaughlin observations
E. K. Simpson, D. Pollacco, G. Hebrard +7
We present an observation of the Rossiter-McLaughlin effect for the planetary system WASP-3. Radial velocity measurements were made during transit using the SOPHIE spectrograph at…
Extrasolar planets and brown dwarfs around A-F type stars - VII. Theta Cygni radial velocity variations: planets or stellar phenomenon?
M. Desort, A. -M. Lagrange, F. Galland +23
(abridged) In the frame of the search for extrasolar planets and brown dwarfs around early-type main-sequence stars, we present the results obtained on the early F-type star Theta…
The SOPHIE northern extrasolar planets. I. A companion close to the planet/brown-dwarf transition around HD16760
F. Bouchy, G. Hebrard, S. Udry +2
We report on the discovery of a substellar companion or a massive Jupiter orbiting the G5V star HD16760 with the spectrograph SOPHIE installed on the OHP 1.93-m telescope. Characte…
Spin-orbit misalignment in the HD80606 planetary system
F. Pont, G. Hebrard, J. M. Irwin +5
We recently reported the photometric and spectroscopic detection of the primary transit of the 111-day-period, eccentric extra-solar planet HD80606 b, at Observatoire de Haute-Prov…
Photometric and spectroscopic detection of the primary transit of the 111-day-period planet HD 80606 b
C. Moutou, G. Hebrard, F. Bouchy +19
We report the detection of the primary transit of the extra-solar planet HD 80606 b, thanks to photometric and spectroscopic observations performed at Observatoire de Haute-Provenc…
