HD 147018, 171238 and 204313 radial velocities
Listed in IVOA Registry (Virtual Observatory)
We report the detection of a double planetary system around HD140718 as well as the discovery of two long period and massive planets orbiting HD171238 and HD204313.
Description
Those discoveries were made with the CORALIE Echelle spectrograph mounted on the 1.2-m Euler Swiss telescope located at La Silla Observatory, Chile. The planetary system orbiting the nearby G9 dwarf HD147018 is composed of an eccentric inner planet (e=0.47) with twice the mass of Jupiter (2.1M_Jup_) and with an orbital period of 44.24-days.
The outer planet is even more massive (6.6M_Jup_) with a slightly eccentric orbit (e=0.13) and a period of 1008-days. The planet orbiting HD171238 has a minimum mass of 2.6M_Jup_, a period of 1523-days and an eccentricity of 0.40. It orbits a G8 dwarfs at 2.5AU.

The last planet, HD204313 b, is a 4.0 M_Jup_-planet with a period of 5.3-years and has a low eccentricity (e=0.13). It orbits a G5 dwarfs at 3.1AU. The three parent stars are metal rich, which further strengthened the case that massive planets tend to form around metal rich stars.
