An international team, including one scientist from GEPI, discovered three planetary companions around M 67 stars. They used spectroscopic data observed by 4 telescopes (193cm at OHP with SOPHIE spectrograph, HARPS attached to the 3m60 at ESO La Silla, CORALIE on the Eurler telescope at La Silla, and Hobby Eberly Telescope in Texas, USA).
More details can be found in the press-release from Observatoire de Paris and the one from ESO.
