オート＝プロヴァンス天文台
The Jupiter-mass hot Jupiter was independently discovered orbiting the primary star by two different teams using doppler spectroscopy. One group led by Claire Moutou used the ELODIE spectrograph at the Haute-Provence Observatory in France while John Asher Johnson and collaborators used the Coudé Auxiliary and C. Donald Shane telescopes at Lick Observatory in California. The planet takes 6.8 days to orbit at 0.077 AU from the primary star in an eccentric orbit.
