SOPHIE velocimetry of Kepler transit candidates. XIX. The transiting temperate giant planet KOI-3680b
G. Hebrard, A. S. Bonomo, R. F. Diaz +15
Whereas thousands of transiting giant exoplanets are known today, only a few are well characterized with long orbital periods. Here we present KOI-3680b, a new planet in this categ…
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…
Reconciling the predictions of microlensing analysis with radial velocity measurements for OGLE-2011-BLG-0417
E. Bachelet, J. -P. Beaulieu, I. Boisse +2
Microlensing is able to reveal multiple body systems located several kilo-parsec away from the Earth. Since it does not require the measurement of light from the lens, microlensing…
The SOPHIE search for northern extrasolar planets XIII. Two planets around M-dwarfs Gl617A and Gl96
M. J. Hobson, R. F. Díaz, X. Delfosse +32
We report the detection of two exoplanets and a further tentative candidate around the M-dwarf stars Gl96 and Gl617A, based on radial velocity measurements obtained with the SOPHIE…
An Earth-sized exoplanet with a Mercury-like composition
A. Santerne, B. Brugger, D. J. Armstrong +43
The Earth, Venus, Mars, and some extrasolar terrestrial planets have a mass and radius that is consistent with a mass fraction of about 30% metallic core and 70% silicate mantle. A…
SOPHIE velocimetry of Kepler transit candidates XVIII. Radial velocity confirmation, absolute masses and radii, and origin of the Kepler-419 multiplanetary system
J. M. Almenara, R. F. Díaz, G. Hébrard +14
Kepler-419 is a planetary system discovered by the Kepler photometry which is known to harbour two massive giant planets: [...] Here we present new radial velocity (RV) measurement…
