The `666' collaboration on OGLE transits: I. Accurate radius of the planets OGLE-TR-10b and OGLE-TR-56b with VLT deconvolution photometry
Frederic Pont, Claire Moutou, Michael Gillon +14
Transiting planets are essential to study the structure and evolution of extra-solar planets. For that purpose, it is important to measure precisely the radius of these planets. He…
On the Age of Stars Harboring Transiting Planets
C. Melo, N. C. Santos, F. Pont +5
Results of photometric surveys have brought to light the existence of a population of giant planets orbiting their host stars even closer than the hot Jupiters (HJ), with orbital p…
Kinematics of planet-host stars and their relation with dynamical streams in the solar neighbourhood
A. Ecuvillon, G. Israelian, F. Pont +2
We present a detailed study on the kinematics of metal-rich stars with and without planets, and their relation with the Hyades, Sirius and Hercules dynamical streams in the solar n…
The HARPS search for southern extra-solar planets. IX. mu Ara, a system with four planets
F. Pepe, A. C. M. Correia, M. Mayor +13
The mu Ara planetary system is rather complex: It contains two already known planets, mu Ara b with P=640 days and mu Ara c with P=9.64 days, and a third companion on a wide but st…
Chemical abundances for the transiting planet host stars OGLE-TR-10, 56, 111, 113, 132 and TrES-1. Abundances in different galactic populations
N. C. Santos, A. Ecuvillon, G. Israelian +6
We used the UVES spectrograph (VLT-UT2 telescope) to obtain high-resolution spectra of 6 stars hosting transiting planets, namely for OGLE-TR-10, 56, 111, 113, 132 and TrES-1. The…
A correlation between the heavy element content of transiting extrasolar planets and the metallicity of their parent stars
Tristan Guillot, Nuno C. Santos, Frédéric Pont +3
Nine extrasolar planets with masses between 110 and 430M are known to transit their star. The knowledge of their masses and radii allows an estimate of their composition, but uncer…
