In this paper, we present our HARPS radial-velocity data for eight low-activity solar-type stars belonging to the HARPS volume-limited sample: HD 6718, HD 8535, HD 28254, HD 290327, HD 43197, HD 44219, HD 148156, and HD 156411. Keplerian fits to these data reveal the presence of low-mass companions around these targets. With minimum masses ranging from 0.58 to 2.54 MJup, these companions are in the planetary mass domain. The orbital periods of these planets range from slightly less than one to almost seven years. The eight orbits presented in this paper exhibit a wide variety of eccentricities: from 0.08 to above 0.8.
Key words: planetary systems / techniques: radial velocities / techniques: spectroscopic
Based on observations made with the HARPS instrument on the ESO 3.6-m telescope at the La Silla Observatory (Chile) under the GTO programme ID 072.C-0488.
