The SOPHIE search for northern extrasolar planets: XII. Three giant planets suitable for astrometric mass determination with Gaia
We present new radial velocity measurements for three low-metallicity solar-like stars observed with the SOPHIE spectrograph and its predecessor ELODIE, both installed at the 193 cm telescope of the Haute-Provence Observatory, allowing the detection and characterization of three new giant extrasolar...
