High Accuracy Radial Velocity Planet Searcher 高精度径向速度行星搜索器
(重定向自HARPS)
The High Accuracy Radial velocity Planet Searcher (HARPS) is a high-precision echelle spectrograph installed in 2002 on ESO's 3.6m telescope at La Silla Observatory in Chile. The first light was achieved in February 2003. HARPS has discovered over 130 exoplanets with the first in 2004. It is a second-generation radial-velocity spectrograph, based on experience with the ELODIE and CORALIE instruments.
