Asteroseismology of exoplanets-host stars: a link between the two scientific programmes of COROT
Sylvie Vauclair, Matthieu Castro, Stephane Charpinet +5
Studying the internal structure of exoplanets-host stars compared to that of similar stars without detected planets is particularly important for the understanding of planetary for…
X-ray Flashes or soft Gamma-ray Bursts? The case of the likely distant XRF 040912
G. Stratta, S. Basa, N. Butler +49
In this work, we present a multi-wavelength study of XRF 040912, aimed at measuring its distance scale and the intrinsic burst properties. We performed a detailed spectral and temp…
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…
Biomarkers in disk-averaged near-UV to near-IR Earth spectra using Earthshine observations
Slim Hamdani, Luc Arnold, C. Foellmi +6
We analyse the detectability of vegetation on a global scale on Earth's surface. Considering its specific reflectance spectrum showing a sharp edge around 700 nm, vegetation can be…
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…
No Expanding Fireball: Resolving the Recurrent Nova RS Ophiuchi with Infrared Interferometry
J. D. Monnier, R. K. Barry, W. A. Traub +17
Following the recent outburst of the recurrent nova RS Oph on 2006 Feb 12, we measured its near-infrared size using the IOTA, Keck, and PTI Interferometers at multiple epochs. The…
