translate English to French: Over the past 12 years, researchers have found 250 of these so-called exoplanets, with Mayor's team accounting for about half the discoveries. Most of the Swiss astrophysicist's work is done using an instrument called the Higher Accuracy Radial Velocity Planet Searcher (HARPS), an instrument installed on a 3.6-metre telescope at the European Southern Observatory (ESO) at La Silla in Chile.
