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…
WASP-1b and WASP-2b: Two new transiting exoplanets detected with SuperWASP and SOPHIE
A. Collier Cameron, F. Bouchy, G. Hebrard +36
We have detected low-amplitude radial-velocity variations in two stars, USNO-B1.0 1219-0005465 (GSC 02265-00107 = WASP-1) and USNO-B1.0 0964-0543604 (GSC 00522-01199 = WASP-2). Bot…
The effect of red noise on planetary transit detection
Frederic Pont, Shay Zucker, Didier Queloz
Since the discovery of short-period exoplanets a decade ago, photometric surveys have been recognized as a feasible method to detect transiting hot Jupiters. Many transit surveys a…
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…
Refined parameters of the planet orbiting HD 189733
G. A. Bakos, H. Knutson, F. Pont +13
We report on the BVRI multi-band follow-up photometry of the transiting extrasolar planet HD 189733b. We revise the transit parameters and find planetary radius RP = 1.154+/- 0.032…
