We present the discovery of three new giant planets around three metal-deficient stars: HD 5388 b (1.96 MJup), HD 181720 b (0.37 MJup), and HD 190984 b (3.1 MJup). All the planets have moderately eccentric orbits (ranging from 0.26 to 0.57) and long orbital periods (from 777 to 4885 days). Two of the stars (HD 181720 and HD 190984) were part of a program searching for giant planets around a sample of ∼100 moderately metal-poor stars, while HD 5388 was part of the volume-limited sample of the… Expand

The HARPS search for southern extra-solar planets XXVII. Seven new planetary systems
We are conducting a planet search survey with HARPS since seven years. The volume-limited stellar sample includes all F2 to M0 main-sequence stars within 57.5 pc, where extrasolar planetaryExpand
The GAPS Programme with HARPS-N at TNG XVIII. Two new giant planets around the metal-poor stars HD 220197 and HD 233832
Statistical studies of exoplanets have shown that giant planets are more commonly hosted by metal-rich dwarf stars than low-metallicity ones, while such a correlation is not evident for lower-massExpand
The HARPS search for southern extrasolar planets - XXV. Results from the metal-poor sample
Searching for extrasolar planets around stars of different metallicity may provide strong constraints to the models of planet formation and evolution. In this paper we present the overall results ofExpand
Planetary companions around the metal-poor star HIP 11952
Aims. We carried out a radial-velocity survey to search for planets around metal-poor stars. In this paper we report the discovery of two planets around HIP 11952, a metal-poor star with [Fe/H]=−1.9Expand
HD 5388 b is a 69 MJup companion instead of a planet
We examined six exoplanet host stars with non-standard Hipparcos astrometric solution, which may be indicative of unrecognised orbital motion. Using Hipparcos intermediate astrometric data, weExpand
The frequency of giant planets around metal-poor stars
Context. The discovery of about 700 extrasolar planets, so far, has lead to the first statistics concerning extrasolar planets. The presence of giant planets seems to depend on stellar metallicityExpand
The GAPS programme with HARPS-N at TNG - II. No giant planets around the metal-poor star HIP 11952
In the context of the programme Global Architecture of Planetary Systems (GAPS), we have performed radial velocity monitoring of the metal-poor star HIP 11952 on 35 nights during about 150 days usingExpand
The visitor from an ancient galaxy: A planetary companion around an old, metal-poor red horizontal branch star
Abstract We report the detection of a planetary companion around HIP 13044, a metal-poor red horizontal branch star belonging to a stellar halo stream that results from the disruption of an ancientExpand
The SOPHIE search for northern extrasolar planets - IX. Populating the brown dwarf desert
Radial velocity planet search surveys of nearby solar-type stars have shown a strong scarcity of brown dwarf companions within similar to 5 AU. There is presently no comprehensive explanation forExpand
The SOPHIE search for northern extrasolar planets - V. Follow-up of ELODIE candidates: Jupiter-analogs around Sun-like stars
We present radial-velocity measurements obtained in one of a number of programs underway to search for extrasolar planets with the spectrograph SOPHIE at the 1.93-m telescope of the Haute-ProvenceExpand
