Accurate radial velocities of stars measured with high-resolution spectrographs constitute a powerful technique to detect and study exoplanetary systems. That indirect method allowed the first exoplanets to be discovered and continues providing numerous results. The SOPHIE environmentally stabilized echelle spectrograph at Haute-Provence Observatory 1.93-m telescope, France, is widely used for such studies in the optical domain. SOPHIE is employed to perform radial velocity surveys in different stellar samples or for the follow-up of photometric surveys for transiting planets. Those programs yield new detections and characterizations in an increasing parameters space. I will present the SOPHIE instrument and programs, and some of their recent results in exoplanetary science.
