HARPS

(High Accuracy Radial Velocity Planet Searcher)
(high-precision spectrograph for exoplanet searches)

HARPS (High Accuracy Radial Velocity Planet Searcher) is a spectrograph with an echelle grating in the ESO 3.6m Telescope at La Silla Observatory (LSO) in Chile. It is designed for the radial velocity method, with a combination of spectral resolution and ability to detect very small wavelength differences that make it capable of detecting radial-velocity differences down to 1 meter per second. It began operation in 2003 and is credited with discovering at least 130 extra-solar planets. HARPSpol is a term for HARPS using its polarimeter feature. The HARPS M dwarf sample is a astronomical catalog of about 400 M dwarfs used for a study.
