cds-question@unistra.frglobular-star-clustersvariable-starsmetallicityWe present new spectroscopic metal abundances for 74 RR Lyrae (RRL) stars in {omega} Cen obtained with FLAMES. The well-known metallicity spread is visible among the RRL variables. The metal-intermediate (MI) RRL stars ([Fe/H]~-1.2) are fainter than the bulk of the dominant metal-poor population ([Fe/H]~-1.7), in good agreement with the corresponding zero-age horizontal-branch models with cosmological helium abundance Y=0.246.2006ApJ...640L..43Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/640/L43CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/424/1101 : Variable Stars in the field of {omega} Cen (Kaluzny+, 2004)J/A+A/420/173 : JK photometry of Omega Cen red giants (Sollima+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/640/L43https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/640/L43http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/640/L43https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/640/L43https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/640/L43http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/640/L43GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/640/L43/table1 (Metallicities and properties of the target RRLyrae)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/640/L43/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/640/L43/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/640/L43/table1?GETtext/xml+votable180.050000true201.5763333-47.38686110.0055555555555555566/43225 43227https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/640/L43?format=asciiOpticaldefaultJ/ApJ/640/L43/table1Metallicities and properties of the target RRLyraePerPerioddtime.periodfloatRRtThe RR type: 1=RRab, 0=RRcmeta.code;src.varintrecnoRecord number assigned by the VizieR team.
