Didier Queloz (born February 23, 1966) is a Geneva-based astronomer with a prolific record in finding extrasolar planets. He is understudy to Michel Mayor.
Didier Queloz was a Ph.D. student at the University of Geneva when he and Michel Mayor discovered the first exoplanet around a main sequence star. Queloz performed an analysis on 51 Pegasi using radial velocity measurements (doppler effect), and was astonished to find a planet with an orbital period of 4.2 days. He had been performing the analysis as an exercise to hone his skills.[1] The planet, 51 Pegasi b, challenged the then accepted views of planetary formation, being a hot jupiter or roaster.
