We report on the first extra-solar planet discovered with the brand new HARPS instrument. The planet is a typical "hot Jupiter" with m2 sini = 0.62 MJup and an orbital period of 3.39 days, but from the photometric follow-up of its parent star HD 330075 we can exclude the presence of a transit. The induced radial-velocity variations exceed 100 m s −1 in semi-amplitude and are easily detected by state-of-the-art spectro-velocimeters. Nevertheless, the faint magnitude of the parent star (V = 9.36…

The HARPS search for southern extra-solar planets - III. Three Saturn-mass planets around HD 93083, HD 101930 and HD 102117
We report on the detection of three Saturn-mass planets discovered with the HARPS instrument. HD 93083 shows radial-velocity (RV) variations best explained by the presence of a companion of 0.37 M
The HARPS search for southern extra-solar planets - V. A 14 Earth-masses planet orbiting HD 4308
We present here the discovery and characterisation of a very light planet around HD4308. The planet orbits its star in 15.56 days. The circular radial-velocity variation presents a tiny

We report the discovery of six new substellar companions of main-sequence stars, detected by multiple Doppler measurements with the instrument HARPS installed on the ESO 3.6 m telescope, La Silla,
The HARPS search for southern extra-solar planets - XX. Planets around the active star BD -08°2823
We report the detection of a planetary system around BD-08 degrees 2823 that includes at least one Uranus-mass planet and one Saturnmass planet. This discovery serendipitously originates from a
The HARPS search for southern extra-solar planets - XXXI. The M-dwarf sample
Searching for planets around stars with different masses helps us to assess the outcome of planetary formation for different initial conditions. The low-mass M dwarfs are also the most frequent stars
The HARPS search for southern extra-solar planets. X. A m sin i = 11 M_â planet around the nearby spotted M dwarf GJ 674
Context. How planet properties depend on stellar mass is a key diagnostic of planetary formation mechanisms. Aims. This motivates planet searches around stars that are significantly more massive or
