Elodie spectrograph

The Elodie spectrograph covered with its thermal insulation.


Elodie is a high-resolution échelle spectrograph in operation at the Haute-Provence Observatory and used in the detection of the first exoplanet, 51 Pegasi. It is fed by a fiber-optic bundle from the Cassegrain focus of the Observatory's 1.93-meter telescope. An improved version of Elodie, known as Coralie, is in operation in the southern hemisphere.
