Spring 1994: First measurements for the OHP-Planet Search by Mayor & Queloz.
Summer 1994: the radial-velocity variability of 51 Peg is detected.
Summer 1995: the radial-velocity periodic signal of 51 Peg is still present: the first Extrasolar Planet is about to be announced.
October the 5th 1995: The detection of the first Extrasolar Planets, in orbit around 51 Peg, is announced by Mayor & Queloz during the 9th Cambridge Workshop on "Cool Stars, Stellar Systems and the Sun" in Florence, Italy.
October the 12th 1995: Marcy & Butler start their radial-velocity follow-up of 51 Peg. They rapidly confirm the detection.
Spring 1996: Hardware improvement of ELODIE. A fiber scrambling device is installed improving the precision
Spring 1996: Beginning of the second OHP-Planet Search Survey (enlarged stellar sample: > 320 stars). This programme is still underway.
Summer 1998: 2 Extrasolar Planets detected with ELODIE: around GJ 876 and 14 Herculis
Summer 1999: the Planetary Companion orbiting HD 209458 is detected in collaboration with the G-Dwarf Planet Search Team (Latham, Mazeh et al., using the HIRES spectrograph mounted on the KECK1-10m Telescope in Hawaii). The transit times are determined.
September 1999: using ELODIE-G Dwarf transit times predictions, 2 full transits of the Planet around HD 209458 are measured by David Charbonneau and Tim Brown (STARE Project).
November 1999: the detection of the transits of the Planet around HD 209458 is announced.
August the 7th 2000: the Planetary Companion to HD 190228 is announced by the ELODIE Team at the IAU General Assembly in Manchester.
April the 4th 2001: 3 new Planets (around HD 8574, HD 50554, HD 106252) + 1 Planetary System (around HD 74156) are announced by the ELODIE Team. Moreover, 2 Extrasolar Planets (around HD 80606 and HD 178911B) are announced by the ELODIE Team in collaboration with the G Dwarf Planet Search Team.
