The CORALIE spectrograph is an echelle type spectrograph used for astronomy. This instrument used with a telescope to measure star spectra for the Doppler effect to detect the presence of extrasolar planets by the radial velocity method. This instrument was installed on the 1.2m Euler Swiss Telescope at the ESO La Silla Observatory in Chile for the Southern Sky extrasolar Planet search Programme.[1]

Characteristics[edit]

The resolution of CORALIE is fixed at R = 50,000 with a 3 pixel sampling. The detector CCD is 2k X 2k with a 15 micrometer pixel size.

Planets discovered by CORALIE[edit]

Five planetary object have been discovered using CORALIE along with several confirmations of discoveries by other programs.
