Stéphane Udry




Stéphane Udry (born 1961 in Sion, Switzerland) is an astronomer at the University of Geneva in Switzerland, whose current work is primarily the search for extra-solar planets. He and his team, in 2007, discovered a possibly terrestrial planet in the habitable zone of the red dwarf star Gliese 581, approximately 20 light years away in the constellation Libra. He also led the observational team that discovered HD 85512 b, another most promisingly habitable exoplanet.

Udry earned a doctorate at the University of Geneva in 1992, and spent two years at Rutgers University in New Jersey. Later, Udry returned to Geneva, and worked with Michel Mayor, the discoverer of 51 Pegasi b, the first extrasolar planet found revolving around a normal star. In 2007, Udry was appointed full professor in the faculty of natural sciences at the University of Geneva.

The course will provide an overview of the knowledge acquired during the past 20 years in the domain of exoplanets. It will review the different detection methods, their limitations, and the information provided on the orbital system and the planet itself, and how this information is helping our understanding of planet formation.
