We report the detection of the primary transit of the extra-solar planet HD 80606 b, thanks to photometric and spectroscopic observations performed at Observatoire de Haute-Provence, simultaneously...
Accurate masses of very low mass stars: I Gl 570BC (0.6+0.4 Msol) (1999)
Forveille, Thierry, Beuzit, Jean Luc, Delfosse, Xavier, Segransan, Damien, Beck, Francoise, Mayor, Michel, ...
We present very accurate individual masses (1.2% relative accuracy) for the two components of Gl 570BC, an interferometric and double-lined spectroscopic binary system. They were obtained from new...
The closest extrasolar planet: A giant planet around the M4 dwarf Gl 876 (1998)
Delfosse, Xavier, Forveille, Thierry, Mayor, Michel, Perrier, Christian, Naef, Dominique, Queloz, Didier
High precision radial velocity observations of the nearby M4 dwarf Gl 876 with the Observatoire de Haute Provence 1.93 m telescope and the new 1.20 m swiss telescope at la Silla indicate the presence...
