The HARPS search for southern extra-solar planets. XX. Planets around the active star BD-08:2823

G. Hebrard, S. Udry, G. Lo Curto +13

We report the detection of a planetary system around BD-08:2823, that includes at least one Uranus-mass planet and one Saturn-mass planet. This discovery serendipitously originates…

Search for Carbon Monoxide in the atmosphere of the Transiting Exoplanet HD189733b

Jean-Michel Desert, Alain Lecavelier des Etangs, Guillaume Hebrard +4

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 t…
