cds-question@unistra.frchemically-peculiar-starsradial-velocitymetallicityspectroscopysolar-system-planetsWe present an analysis of three years of precision radial velocity (RV) measurements of 160 metal-poor stars observed with HIRES on the Keck 1 telescope. We report on variability and long-term velocity trends for each star in our sample. We identify several long-term, low-amplitude RV variables worthy of followup with direct imaging techniques. We place lower limits on the detectable companion mass as a function of orbital period. Our survey would have detected, with a 99.5% confidence level, over 95% of all companions on low-eccentricity orbits with velocity semiamplitude K>~100m/s, or M_p_sini>~3.0M_J_(P/yr)^(1/3)^, for orbital periods P<~3yr. None of the stars in our sample exhibits RV variations compatible with the presence of Jovian planets with periods shorter than the survey duration.2009ApJ...697..544Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/697/544CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/526/A112 : Radial velocities of HARPS metal-poor sample (Santos+, 2011)J/A+A/527/A63 : Radial velocities of 7 new HARPS planetary systems (Moutou+,J/A+A/523/A15 : HARPS XXIII: RV data for the 8 targets (Naef+, 2010)J/A+A/524/A25 : Radial Velocities on 6 exoplanet host stars (Triaud+, 2010)J/A+A/512/A47 : Radial velocities of 3 stars with giant planets (Santos+,J/A+A/496/513 : RV of 6 stars with long-period giant planets (Moutou+, 2009)J/ApJ/652/1585 : Bright metal-poor stars from HES survey (Frebel+, 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/697/544https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/697/544http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/697/544https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/697/544https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/697/544http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/697/544GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/697/544/sample (Target list of the Keck HIRES metal-poor planet survey , radial-velocity results and variability analysis)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/697/544/sample?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/697/544/sample?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/697/544/sample?GETtext/xml+votable180.050000true4.086958316.64636110.0055555555555555566/23 47 373 710 733 758 798 944 1556 1583 1626 1642 2133 2141 2488 3072 3444 4455 4526 5589 5614 5793 6256 6277 6679 6721 6793 7016 7087 7141 7565 7683 8195 8235 8253 8802 8873 9058 9082 10426 10579 10886 11004 11176 11263 11270 11512 11612 11935 12332 12451 12650 12704 12714 12854 12901 13028 13055 13075 13162 14534 14778 14881 14931 15009 15722 15727 15818 16759 17245 17332 17564 17726 17795 17923 17947 17952 18035 18561 18827 18839 18867 18883 19179 19217 19272 19626 19848 20020 20082 21128 22048 22518 22527 22754 23015 23096 23213 23785 23886 24048 24099 24249 24353 26292 26305 26324 26522 26576 27255 27661 27915 27981 28038 28336 28421 28664 29006 29765 29833 29941 29958 30047 30166 30196 30233 30296 30577 30622 30907 30974 31048 31100 31172 31347 31503 31520 31650 31770 31772 32100 32335 32506 32751 36527 36586 43001 44015 44426 44653 44816 44951 45022 48495 48731 48736 48763 48846 49035https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/697/544?format=asciiOpticaldefaultJ/ApJ/697/544/velocRadial velocity measurements for starsrecnoRecord number assigned by the VizieR team.
