Extrasolar planets and brown dwarfs around AF-type stars. X.The SOPHIE northern sample. Combining the SOPHIE and HARPS surveys to compute the close giant planet mass-period distribution around AF-type stars
S. Borgniet, A. -M. Lagrange, N. Meunier +31
The impact of the stellar mass on the giant planet properties is still to be fully understood. Main-Sequence (MS) stars more massive than the Sun remain relatively unexplored in ra…
The GJ 504 system revisited. Combining interferometric, radial velocity, and high contrast imaging data
M. Bonnefoy, K. Perraut, A. -M. Lagrange +79
The G-type star GJ504A is known to host a 3 to 35 MJup companion whose temperature, mass, and projected separation all contribute to make it a test case for the planet formation th…
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…
The Earth as an extrasolar transiting planet: Earth's atmospheric composition and thickness revealed by Lunar eclipse observations
Alfred Vidal-Madjar, Luc Arnold, David Ehrenreich +24
An important goal within the quest for detecting an Earth-like extrasolar planet, will be to identify atmospheric gaseous bio-signatures. Observations of the light transmitted thro…
The SOPHIE search for northern extrasolar planets III. A Jupiter-mass companion around HD 109246
I. Boisse, A. Eggenberger, N. C. Santos +22
We report the detection of a Jupiter-mass planet discovered with the SOPHIE spectrograph mounted on the 1.93-m telescope at the Haute-Provence Observatory. The new planet orbits HD…
Observation of the full 12-hour-long transit of the exoplanet HD80606b. Warm-Spitzer photometry and SOPHIE spectroscopy
G. Hebrard, J. -M. Desert, R. F. Diaz +24
We present new observations of a transit of the 111-day-period exoplanet HD80606b. Using the Spitzer Space Telescope and its IRAC camera on the post-cryogenic mission, we performed…
