Didier Queloz (born on 23 February 1966) is a Swiss astronomer and professor at the University of Geneva and the University of Cambridge[1] and a fellow of Trinity College, Cambridge.[2] He shared one fourth of the 2019 Nobel Prize in Physics.[3][4]

Early life

Queloz was born in Switzerland, on 23 February 1966.[5][6]

Career

In 1995, Queloz was a PhD candidate at the University of Geneva when he and Michel Mayor, his doctoral advisor, discovered the first exoplanet around a main sequence star.[7] For this achievement, they were awarded half of the 2019 Nobel Prize in Physics "for the discovery of an exoplanet orbiting a solar-type star".

Queloz performed an analysis on 51 Pegasi using radial velocity measurements (Doppler spectroscopy) with the ELODIE spectrograph in the Haute-Provence Observatory 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.[8] The planet, 51 Pegasi b, challenged the then accepted views of planetary formation, being a hot Jupiter or roaster.

He has received the 2011 BBVA Foundation Frontiers of Knowledge Award of Basic Sciences (co-winner with Mayor) for developing new astronomical instruments and experimental techniques that led to the first observation of planets outside the solar system. In 2017, he received the Wolf Prize in Physics.[9] In 2019, he was awarded the Nobel Prize in Physics together with Mayor and along with Jim Peebles.[4]
