We recently reported on the detection of a possible planetary-mass companion to Beta Pictoris at a projected separation of 8 AU from the star, using data taken in November 2003 with NaCo, the...
Search for Carbon Monoxide in the atmosphere of the Transiting Exoplanet HD189733b (2009)
Desert, Jean-Michel, Etangs, Alain Lecavelier Des, Hebrard, Guillaume, Sing, David K., Ehrenreich, David, Ferlet, Roger, ...
Water, methane and carbon-monoxide are expected to be among the most abundant molecules besides molecular hydrogen in the hot atmosphere of close-in EGPs. Transit observations in the mid-IR allow the...

Are extrasolar oceans common throughout the Galaxy? (2007)
Ehrenreich, David, Cassan, Arnaud
Light and cold extrasolar planets such as OGLE 2005-BLG-390Lb, a 5.5 Earth-mass planet detected via microlensing, could be frequent in the Galaxy according to some preliminary results from...
A Spitzer Search for Water in the Transiting Exoplanet HD189733b (2007)
Ehrenreich, David, Hébrard, Guillaume, Lecavelier Des Etangs, Alain, K Sing, David, Désert, Jean-Michel, Bouchy, François, ...
We present Spitzer Space Telescope observations of the extrasolar planet HD189733b primary transit, obtained simultaneously at 3.6 and 5.8 microns with the Infrared Array Camera. The system...
En un peu plus d'une dizaine d'années, plusieurs centaines de planètes ont été découvertes en orbite autour d'étoiles autres que le Soleil. Cependant, en-dehors de leurs masses, peu de choses...
