Guillaume Hébrard – Institut d’astrophysique de Paris et Observatoire de Haute-Provence


The first planet in orbit around a star similar to the Sun was discovered in 1995 at Observatoire de Haute-Provence, France. This was a real revolution in astrophysics. Nearly 5000 other extrasolar planets have been detected since then, using radial velocity and transit methods from ground and space observatories, as well as complementary technics. These discoveries contribute to the exploration of our universe by revealing the diversity of planetary systems, put constraints on their formation and evolution processes, allow numerous follow-up studies and observations, and open the way to the detection of potentially habitable planets.
