cds-question@unistra.frglobular-star-clustersdwarf-starschemical-abundancesA discrepancy has emerged between the cosmic lithium abundance inferred by the WMAP satellite measurement coupled with the prediction of the standard big-bang nucleosynthesis theory, and the constant Li abundance measured in metal-poor halo dwarf stars (the so-called Spite plateau). Several models are being proposed to explain this discrepancy, involving either new physics, in situ depletion, or the efficient depletion of Li in the pristine Galaxy by a generation of massive first stars. The realm of possibilities may be narrowed considerably by observing stellar populations in different galaxies, which have experienced different evolutionary histories. The omega Centauri stellar system is commonly considered as the remnant of a dwarf galaxy accreted by the Milky Way. We investigate the lithium content of a conspicuous sample of unevolved stars in this object.2010A&A...519L...3Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/519/L3CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/462/241 : Ca abundance for omega Cen red giants (Norris+ 1996)J/ApJ/667/911 : Abundances on the main sequence of omega Cen (Stanford+, 20007)J/A+A/527/A18 : EW of 6 subgiants of omega Cen (Pancino+, 2011)J/A+A/534/A53 : Equivalent widths of 18 subgiant of omega Cen (Pancino+, 2011)J/MNRAS/357/265 : BVI photometry of omega Cen red giants (Sollima+, 2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/519/L3https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/519/L3http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/519/L3https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/519/L3https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/519/L3http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/519/L3GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/519/L3/stars (Basic data for the Main-Sequence/Sub-Giant Branch stars studied, including anomalous sub-giants)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/519/L3/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/519/L3/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/519/L3/stars?GETtext/xml+votable180.050000true201.6534167-47.59874720.0055555555555555566/43225 43227https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/519/L3?format=asciidefaultJ/A+A/519/L3/starsBasic data for the Main-Sequence/Sub-Giant Branch stars studied, including anomalous sub-giantsrecnoRecord number assigned by the VizieR team.
