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…

SOPHIE velocimetry of Kepler transit candidates. I. Detection of the low-mass white dwarf KOI-74b

David Ehrenreich, Anne-Marie Lagrange, François Bouchy +19

The Kepler mission has detected transits and occultations of a hot compact object around an early-type star, the Kepler Object of Interest KOI 74. The mass of this transiting objec…

OGLE-2005-BLG-153: Microlensing Discovery and Characterization of A Very Low Mass Binary

K. -H. Hwang, A. Udalski, C. Han +77

The mass function and statistics of binaries provide important diagnostics of the star formation process. Despite this importance, the mass function at low masses remains poorly kn…

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…
