High Accuracy Radial Velocity Planet Searcher

From Wikipedia, the free encyclopedia

The High Accuracy Radial velocity Planet Searcher (HARPS) is a high-precision echelle spectrograph installed in 2002 with first light achieved February 2003 on ESO's 3.6m telescopes at La Silla Observatory. It is used for a radial velocity survey of 1000 stars and can attain a precision of 1 m/s, one of only two instruments worldwide with such accuracy.

The principal investigator on HARPS is Michel Mayor, who works with Didier Queloz on it.
