cds-question@unistra.frglobular-star-clustersradial-velocitychemical-abundancesUsing six-dimensional phase-space information from the Fourth Data release of the RAdial Velocity Experiment (RAVE) over the range of Galactic longitude 240{deg}<l<360{deg} and VLSR<-239km/s, we computed orbits for 329 RAVE stars that were originally selected as chemically and kinematically related to Omega Centauri. The orbits were integrated in a Milky-Way-like axisymmetric Galactic potential, ignoring the effects of the dynamical evolution of Omega Centauri due to the tidal effects of the Galaxy disk on the cluster along time. We also ignored secular changes in the Milky Way potential over time. In a Monte Carlo scheme, and under the assumption that the stars may have been ejected with velocities greater than the escape velocity (V_rel_>V_esc,0_) from the cluster, we identified 15 stars as having close encounters with Omega Centauri: (i) 8 stars with relative velocities V_rel_<200km/s may have been ejected ~200Myr ago from Centauri; (ii) another group of 7 stars were identified with high relative velocity V_rel_>200km/s during close encounters, and it seems unlikely that they were ejected from Omega Centauri. We also confirm the link between J131340.4-484714 as a potential member of Omega Centauri, and probably ejected ~2.0Myr ago, with a relative velocity V_rel_~80km/s.2015A&A...583A..76Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/583/A76CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIII/272 : RAVE 4th data release (Kordopatis+, 2013)J/AJ/142/193 : RAVE stellar elemental abundances (DR1) (Boeche+, 2011)J/ApJ/722/1373 : {omega} Centauri giants abundances (Johnson+, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/583/A76https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/583/A76http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/583/A76https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/583/A76https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/583/A76http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/583/A76GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/583/A76/tablea1 (Omega Centauri candidates selected from RAVE catalog, their abundance ratios, and space velocities)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/583/A76/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/583/A76/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/583/A76/tablea1?GETtext/xml+votable180.050000true198.4184583-48.78716670.0055555555555555566/16428 24661 24726 24783 24833 24871 24881 24925 24940 24950 24985 25167 25241 25274 25323 25359 25367 25475 25504 25533 25540 25569 25689 25698 25721 25777 25909 26114 26149 26647 26650 26660 26665 26933 26957 27017 27030 30760 30851 30888-30889 31361 32792 32796 32817 32839 32886 32908 32967 33104 33161 33188 33286 33323 33408 33429 33511 33516-33517 33551 33598 33612 33641 33833 33860 33922 33984 34031 34083 34141 34172 34240 34481 34505 34826 34831 34841 34854 34894 35033 35069 35084 35087 35105 35110 35233 35251 35253 35261 35359 35451 35508 35589 35722 36954 37039 37147 37182 37541 37663 37670 37999 38096 38119 38205 38209 38225 38310 38465 38467 38648 38688 38701 38743 38951 39016 39058 39167 39205 39446 39463 39473 39492 39496 39531 39546 39562 39609 39611 39647 39672 39680 39832 40078 40194 40210 40330 40379 40529 40768 40778 41012 41070 41083 41095 41116 41137 41143 41148 41159 41163 41189 41191 41259 41329 41554 41557 41618 41978 42009 42037-42038 42048 43099 43103 43215 43365 43379 43413 43421 43556 43569 43610 43623 43641 43681 43975 44000 44035 44188 44217 44237 44252 44275 44287 44398 44414-44415 44421 44429 44437 44466 44480 44515 44573 44576 44624 44635 44718 44762 44783 44785 44810 44820 44831 44847 44855 44861 44872 44875 44882 44889 44922 44967 45019 45037 45092 45115 45220 45225 45289 45331 45357 45399 45412-45413 45441 45444 45456 45492 45543 45571 45592-45593 45615 45628 45633 45636 45659 45719 45725 45727 45754 45774-45775 45778 45790 45792 45801 45828 45841 45850 45866 45924 45934 45966 45980-45981 45994 46082 46093 46095 46129 46141 46165 46187 46198 46210 46263 46326 46422 46441 46446 46488 46611 46661 46683 46733 46755 46760 47116 47123 47125 47128 47130 47161 47182 47188 47207 47221 47231 47311 47313 47324-47325 47335 47351 47368 47384 47399 47417 47497 47501 47509 47717 47728 47733 47779 47782 47873 47875https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/583/A76?format=asciiOpticaldefaultJ/A+A/583/A76/tablea1Omega Centauri candidates selected from RAVE catalog, their abundance ratios, and space velocitiesrecnoRecord number assigned by the VizieR team.
