The CORALIE survey for southern extrasolar planets. V. 3 new extrasolar planets

We report the detection of 3 new planetary companions orbiting the solar-type stars GJ 3021, HD 52265 and HD 169830 using radial-velocity measurements taken with the CORALIE echelle spectrograph. All these planetary companions have longer orbital periods than the 51 Peg-like objects. The orbits are fairly eccentric. The minimum masses of these planets range from 1 to 3.3 {M_Jup}. The stars have spectral types from F8V to G6V. They are metal-rich. We also present our radial-velocity measurements for three solar-type stars known to host planetary companions iota Hor (HD 17051, HD 210277 and HD 217107. Based on data obtained with the CORALIE echelle spectrograph mounted on the 1.2-m ``Leonard Euler'' Swiss telescope at ESO-La Silla Observatory (Chile)
