Pumping the eccentricity of exoplanets by tidal effect
Alexandre C. M. Correia, Gwenaël Boué, Jacques Laskar
Planets close to their host stars are believed to undergo significant tidal interactions, leading to a progressive damping of the orbital eccentricity. Here we show that, when the…
The HARPS search for southern extra-solar planets XXXI. The M-dwarf sample
X. Bonfils, X. Delfosse, S. Udry +11
(Abridged) Searching for planets around stars with different masses probes the outcome of planetary formation for different initial conditions. This drives observations of a sample…
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. V. The three hot Jupiters KOI-135b, KOI-204b and KOI-203b (alias Kepler-17b)
A. S. Bonomo, G. Hébrard, A. Santerne +7
We report the discovery of two new transiting hot Jupiters, KOI-135b and KOI-204b, that were previously identified as planetary candidates by Borucki et al. 2011, and, independentl…
Tidal dissipation in multi-planet systems and constraints to orbit-fitting
Jacques Laskar, Gwenaël Boué, Alexandre C. M. Correia
We present here in full details the linear secular theory with tidal damping that was used to constraint the fit of the HD10180 planetary system in (Lovis et al. 2011). The theory…
Transit-timing measurements with the model-independent barycenter method: Application to the LHS 6343 system
M. Oshagh, G. Boué, N. Haghighipour +3
We present a model-independent technique for calculating the time of mid-transits. This technique, named "barycenter method", uses the light-curve's symmetry to determine the trans…
