We present radial-velocity measurements obtained with the ELODIE and AFOE spectrographs for GJ 777 A (HD 190360), a metal-rich ([Fe /H] = 0.25) nearby ( d= 15.9 pc) star in a stellar binary system. A long-period low ra dial-velocity amplitude variation is detected revealing the presence of a J vian planetary companion. Some of the orbital elements re main weakly constrained because of the smallness of the signal co mpared to our instrumental precision. The detailed orbital sh pe is therefore… CONTINUE READING
