cds-question@unistra.frchemically-peculiar-starssolar-system-planetsradial-velocitymetallicitySearching 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 of a HARPS (a high-precision spectrograph mostly dedicated to deriving precise radial velocities) program to search for planets orbiting a sample of 104 metal-poor stars (selected [Fe/H] below -0.5). Radial velocity time series of each star are presented and searched for signals using several statistical diagnostics. tars with detected signals are presented, including 3 attributed to the presence of previously announced giant planets orbiting the stars HD171028, HD181720, and HD190984. Several binary stars and at least one case of a coherent signal caused by activity-related phenomena are presented. One very promising new, possible giant planet orbiting the star HD107094 is discussed, and the results are analyzed in light of the metallicity-giant planet correlation. We conclude that the frequency of giant planets orbiting metal-poor stars may be higher than previously thought, probably reflecting the higher precision of the HARPS survey. In the metallicity domain of our sample, we also find evidence that the frequency of planets is a steeply rising function of the stellar metal content, as found for higher metallicity stars.2011A&A...526A.112Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/526/A112CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/474/293 : Radial velocities of GJ 674 (Bonfils+, 2007)J/A+A/469/L43 : Radial velocities of Gl 581 (Udry+, 2007)J/A+A/496/513 : RV of 6 stars with long-period giant planets (Moutou+, 2009)J/A+A/496/521 : Radial velocities of HD45364 (Correia+, 2009)J/A+A/496/527 : Radial velocity of HD 47186 and HD 181433 (Bouchy+, 2009)J/A+A/507/487 : GJ 581 radial velocity curve (Mayor+, 2009)J/A+A/512/A46 : Radial velocities of BD-08 2823 (Hebrard+, 2010)J/A+A/512/A47 : Radial velocities of 3 stars with giant planets (Santos+ 2010)J/A+A/512/A48 : HD125612, HD215497, HIP5158 radial velocities (Lo Curto+ 2010)J/A+A/523/A15 : HARPS XXIII: RV data for the 8 targets (Naef+, 2010)J/A+A/526/A111 : HD 85390, 90156 and 103197 radial velocity (Mordasini+, 2011)J/A+A/526/A141 : HIP 85647 & Gl 676A radial velocities (Forveille+, 2011)J/A+A/527/A63 : 7 new HARPS planetary systems radial velocities (Moutou+ 2011)J/A+A/528/A112 : Radial velocities of HD 10180 (Lovis+, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/526/A112https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/526/A112http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/526/A112https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/526/A112https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/526/A112http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/526/A112GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/526/A112/table1 (List of targets, coordinates and magnitudes)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/526/A112/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/526/A112/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/526/A112/table1?GETtext/xml+votable180.050000true0.2425-11.8236110.0055555555555555566/8235 8296 12424 17047 17206 17249 17358 17744 18615 19097 19217 19466 20495 20661 21550 21696 21809 21989 22118 23096 24775 24853 24876 25015 25136 25981 26305 27255 27661 27741 28706 29521 29596 29717 30233 30825 31480 31503 31650 31813 33273 34684 35152 35994 36540 37164 37232 37252 37789 37831 37995 38138 38216 38283 38288 38566 38986 39006 39030 39149 39316 39984 40944 40965 40988 41107 41163 41460 41591 42166 42928 43001 43068 43280 43287 43310 43567 43641 44608 44653 44683 44816 44910 44951 45446 45682 45721 45837 45907 46053 46076 46171 47137 47674 47752 47930 48163 48260 48335 48490 48731 48736 49028 49042https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/526/A112?format=asciiOpticaldefaultJ/A+A/526/A112/table1List of targets, coordinates and magnitudesStarStar namemeta.id;meta.maincharprimaryrecnoRecord number assigned by the VizieR team.
