cds-question@unistra.frmultiple-starssolar-system-planetsradial-velocityPlanetary companions of a fixed mass induce reflex motions with a larger amplitude around lower-mass stars, which adds to making M dwarfs excellent targets for extra-solar planet searches. The most recent velocimeters with a stability of can detect very low-mass planets out to the habitable zone of these stars. Low-mass small planets are abundant around M dwarfs, and most of the known potentially habitable planets orbit one of these cool stars. Our M-dwarf radial velocity monitoring with HARPS on the ESO 3.6m telescope at La Silla observatory makes a major contribution to this sample. We present here dense radial velocity (RV) time series for three M dwarfs observed over ~five years: GJ 3293 (0.42M_{sun}_), GJ 3341 (0.47M_{sun}_), and GJ 3543 (0.45M_{sun}_). We extracted these RVs through minimum chi^2^ -matching of each spectrum against a stack of all observed spectra for the same star that has a high S/N ratio. We then compared potential orbital signals against several stellar activity indicators to distinguish the Keplerian variations induced by planets from the spurious signals that result from rotational modulation of stellar surface inhomogeneities and from activity cycles.2015A&A...575A.119Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/575/A119CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/469/L43 : Radial velocities of Gl 581 (Udry+, 2007)J/A+A/474/293 : Radial velocities of GJ 674 (Bonfils+, 2007)J/A+A/493/639 : Velocity curves of HD 40307 (Mayor+, 2009)J/A+A/493/645 : Gl 176 radial velocities (Forveille+, 2009)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 curves of HD 47186 & HD 181433 (Bouchy+, 2009)J/A+A/507/487 : GJ 581 radial velocity curve (Mayor+, 2009)J/A+A/511/A21 : Radial velocities of GJ876 planetary system (Correia+, 2010)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 HARPS RV curves (Lo Curto+, 2010)J/A+A/523/A15 : HARPS XXIII: RV data for the 8 targets (Naef+, 2010)J/A+A/526/A111 : Radial velocity of HD 85390, 90156, 103197 (Mordasini+, 2011)J/A+A/526/A112 : Radial velocities of HARPS metal-poor sample (Santos+, 2011)J/A+A/526/A141 : Velocity monitoring of Gl 676A and HIP 12961 (Forveille+ 2011)J/A+A/527/A63 : 7 new HARPS planetary systems RV (Moutou+, 2011)J/A+A/528/A112 : Radial velocities of HD 10180 (Lovis+, 2011)J/A+A/551/A59 : HD103774, HD109271 and BD-061339 RV curves (Lo Curto+, 2013)J/A+A/556/A110 : HARPS radial velocities of GJ 163 (Bonfils+, 2013)J/A+A/566/A35 : Radial velocities of HD 41248 (Santos+, 2014)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/575/A119https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/575/A119http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/575/A119https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/575/A119https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/575/A119http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/575/A119GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/575/A119/stars (Target list)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/575/A119/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/575/A119/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/575/A119/stars?GETtext/xml+votable180.050000true67.148333-25.1711110.0055555555555555566/34301 34767 403591.1166583743361574e-19 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/575/A119?format=asciiOpticaldefaultJ/A+A/575/A119/tablea3GJ 3543 RVs, its uncertainty and activity indicatorsrecnoRecord number assigned by the VizieR team.
