The Euler telescope uses the CORALIE instrument to search for exoplanets. In addition, the telescope uses the multi-purpose EulerCam (ecam), a high precision photometry instrument, and a smaller, piggyback mounted telescope, called "Pisco".[2] Its first discovery was a planet in orbit around Gliese 86, determined to be a hot Jupiter with an orbital period of only 15.8 earth days and about four times the mass of Jupiter.[3] Since then, many other exoplanets have been discovered or examined in follow-up observations.
Together with the Mercator Telescope, Euler was part of the Southern Sky extrasolar Planet search Programme, which has discovered numerous extrasolar planets.[4] It has also been frequently employed for follow-up characterization to determine the mass of exoplanets discovered by the Wide Angle Search for Planets, SuperWASP.[5]
The spectrograph participates in the Southern Sky extrasolar Planet search Programme initiated by Michel Mayor
In 2010 visible camera EulerCam was installed by Didier Queloz. Camera main objective was to measure planet by transit method by supporting ground base program such as Wide Angle Search for Planets . The size of an exoplanet can be estimated using the transit method. By combining the measured size and mass from both methods, it can be determined whether the observed exoplanet is gaseous or rocky.
CharacteristicsEdit
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.

CORALIE spectrograph is an echelle type spectrograph used for astronomy It is a copy of the ELODIE spectrograph used by Michel Mayor and Didier Queloz to detect the planet orbiting a star In April 1998 it was built and installed at the Euler Telescope Later in 2007 it was upgraded by Didier Queloz and his team to increase its performances to support Wide Angle Search for Planets program and Next Generation Transit Survey The instrument is optimized to measure Doppler effect on a star s electromagnetic spectrum with great precision to detect the gravitational tug of an exoplanet orbiting around it 6 7 It also known as radial velocity or wobble method is an indirect detection method The mass of the planet can be estimated from these measurements The spectrograph participates in the
