SOPHIE spectrograph was installed at Haute Provence Observatory in 2006 in
particular to perform various radial velocity surveys to study exoplanets. The goal of
one of the SOPHIE surveys, is to improve the statistics on giant extrasolar planets.
The statistical survey of these giant planets allows us to distinguish between exoplanet
population like super-Earths, giant planets, and brown dwarfs and also to obtain correlation
between the different parameters of these exoplanets and their host stars. It gives us an
opportunity to follow-up multi-planet systems and study their characteristics. Under this
survey, we have detected six new giant long period planets. I will talk about these newly
detected systems.
