cds-question@unistra.fropen-star-clusterslate-type-starsmultiple-starssolar-system-planetsradial-velocityWe present the results of a seven-year-long radial velocity survey of a sample of 88 main-sequence and evolved stars to reveal signatures of Jupiter-mass planets in the solar-age and solar-metallicity open cluster M67. We analysed precise radial velocity (RV) measurements obtained with five different instruments. We conducted Monte Carlo simulations to estimate the occurrence rate of giant planets in our radial velocity survey. All the planets previously announced in this RV campaign with their properties are summarised: 3 hot Jupiters around the main-sequence stars YBP1194, YBP1514, and YBP401, and 1 giant planet around the evolved star S364. Two additional planet candidates around the stars YBP778 and S978 are also analysed. We discuss stars that exhibit large RV variability or trends individually. We find an occurrence of giant planets of ~18.0% in a selected period-mass range. This frequency is slightly higher but consistent within the errors with the estimate for the field stars, leading to the general conclusion that open cluster and field statistics agree. However, we find that the rate of hot Jupiters in the cluster (~5.7%) is substantially higher than in the field.2017A&A...603A..85Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/603/A85CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/484/609 : BVI photometry and proper motions in M67 (Yadav+, 2008)J/A+A/545/A139 : Radial Velocities of stars observed in M67 (Pasquini+, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/603/A85https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/603/A85http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/603/A85https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/603/A85https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/603/A85http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/603/A85GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/603/A85/stars (List of studied stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/603/A85/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/603/A85/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/603/A85/stars?GETtext/xml+votable180.050000true132.784958311.78669440.0055555555555555566/4255 4296 4298https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/603/A85?format=asciiOpticaldefaultJ/A+A/603/A85/starsList of studied starsVCShow the Radial Velocity curvesmeta.ref.urlcharrecnoRecord number assigned by the VizieR team.
