Astrophysician,
Full Professor, Department of Astronomy, University of Geneva, and Director of the Geneva Observatory, Sauverny, Switzerland.

Research interests

Over several years Professor Mayor has developed a spectrograph for measurements of velocities of stars along the line of sight. It is thanks to this instrument, and its successive improvements, that Mayor has attained the extraordinary precision of a few meters per second in these velocities. This has led to the first detection of a planet outside our solar system by Mayor and his postgraduate student Didier Queloz in the year 1995.

Current research topics :
Search for extra-solar planets and brown dwarfs
Radial velocity measurements at intermediate and high precisions (Coravel - Elodie - Coralie)
High resolution Spectroscopy
Radial-velocity standards
Low-mass companions
Luminosity and mass fonctions of the lower Main-Sequence
Binarity among cool stars (G, K and M dwarfs)
Stellar rotation
Galactic kinematics: F-G dwarfs of the solar neighbourhood
Outer disc Cepheids
Coravel - Hipparcos survey
T-Tauri stars
Giant barium and S stars
