The Royal Astronomical Society has announced the award of a Gold Medal to Professor Michel Mayor of the University of Geneva. Prof. Mayor was, of course, the co-discoverer of the first extrasolar planet around a solar-like star, with the detection of 51 Pegasi b back in 1995. His Observatoire de Genève group developed a succession of planet-finding spectrographs that have led the way to the discovery of many hundreds of extrasolar planets.
Prof. Mayor has been an important collaborator for the WASP project, through the CORALIE spectrograph on the 1.2-m Swiss/Euler telescope at La Silla. The CORALIE spectrograph observes all WASP-South planet candidates, and the detection of the radial-velocity signature of a planet — in about 1 in 8 such candidates — is the crucial step that confirms a new planet discovery. Thus Prof. Mayor was a co-author on many of the early WASP planet papers until his retirement.
The WASP project is hugely indebted to Prof. Mayor and is honoured to have collaborated with him on WASP planet discovery. We congratulate him on the well-deserved award of the RAS Gold Medal.
