Why compositional convection cannot explain substellar objects sharp spectral type transitions
Jérémy Leconte
As brown dwarfs and young giant planets cool down, they are known to experience various chemical transitions --- for example from CO rich L-dwarfs to methane rich T-dwarfs. Those c…
SOPHIE velocimetry of Kepler transit candidates. XIII. KOI-189 B and KOI-686 B: two very low-mass stars in long-period orbits
R. F. Díaz, G. Montagnier, J. Leconte +10
We present the radial-velocity follow-up of two Kepler planetary transiting candidates (KOI-189 and KOI-686) carried out with the SOPHIE spectrograph at the Observatoire de Haute P…
Elliptical instability in hot Jupiter systems
David Cébron, Michael Le Bars, Patrice Le Gal +3
Several studies have already considered the influence of tides on the evolution of systems composed of a star and a close-in companion to tentatively explain different observations…
Understanding exoplanet formation, structure and evolution in 2010
G. Chabrier, J. Leconte, I. Baraffe
In this short review, we summarize our present understanding (and non-understanding) of exoplanet formation, structure and evolution, in the light of the most recent discoveries. R…
