View source for Geneva Extrasolar Planet Search

The '''Geneva Extrasolar Planet Search''' is a variety of observational programs run by the [[Geneva Observatory]] at [[Versoix]], a small town near [[Geneva]], [[Switzerland]]. The programs are executed by [[Michel Mayor|M. Mayor]], D. Naef, F. Pepe, [[Didier Queloz|D. Queloz]], N.C. Santos, and [[Stéphane Udry|S. Udry]] using  several telescopes and instruments in the Northern and Southern Hemisphere and have resulted in the discovery of numerous [[extrasolar planets]], including [[51 Pegasi b]], the first ever confirmed exoplanet orbiting a [[main-sequence]] star.

Programs originated at Geneva are generally conducted in collaboration with several other academic institutions from Belgium, Germany, Italy and the United Kingdom. These programs search for exoplanets in various locations using different instruments. These include the [[Haute-Provence Observatory]] in France, the [[TRAPPIST]] and the [[Euler Telescope]], both located at [[La Silla Observatory]] in Chile, as well as the M dwarf programs. Most recent projects involve the [[High Accuracy Radial Velocity Planet Searcher|HARPS]] [[spectrograph]], [[HARPS-N]] at the island of La Palma, and the [[Next-Generation Transit Survey]] located at the [[Paranal Observatory]], northern Chile.<ref>David Darling, "Geneva Extrasolar Planet Search Programs", ''The Encyclopedia of Astrobiology, Astronomy, and Space Flight'', May 7, 2007.</ref><ref>{{ cite web

The Integral Science Data Centre is located at Ecogia, which also belongs to the town of Versoix. The centre is linked to the Geneva Observatory and deals with the processing of the data provided by the satellite [[INTEGRAL]] of the [[European Space Agency]].<ref name="Observatory of Geneva">''Observatory of Geneva'', University of Geneva, May 7, 2007, {{cite web |url=http://www.unige.ch/sciences/astro/an/ |title=Archived copy |access-date=2007-05-08 |url-status=dead |archive-url=https://web.archive.org/web/20050911190232/http://www.unige.ch/sciences/astro/an/ |archive-date=2005-09-11 }}</ref> On the two sites of Sauverny and Ecogia, a group of approximately 143 people are employed, including scientists, PhD candidates, students, technical staff (computer and electronics specialists, mechanics), as well as administrative staff.<ref name="Observatory of Geneva"/>
