cds-question@unistra.frglobular-star-clustersgiant-starschemical-abundancesWe present Li and Fe abundances for 87 stars in the globular cluster M4, obtained by using high-resolution spectra collected with GIRAFFE at the Very Large Telescope. The targets range from the turn-off up to the red giant branch bump. The Li abundance in the turn-off stars is uniform, with an average value equal to A(Li)=2.30+/-0.02dex (sigma=0.10dex), consistent with the upper envelope of Li content measured in other globular clusters and in the halo field stars, confirming also for M4 the discrepancy with the primordial Li abundance predicted by Wilkinson Microwave Anisotropy Probe+ big bang nucleosynthesis (WMAP+BBNS).2011MNRAS.412...81Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/412/81CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/490/625 : Abundances of NGC 6121 red giants (Marino+, 2008)J/ApJ/689/1031 : Heavy element abundances in giant stars (Yong+, 2008)J/A+A/505/117 : Red giants abundances in 15 globular clusters (Carretta+ 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/412/81https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/412/81http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/412/81https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/412/81https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/412/81http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/412/81GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/412/81/table1 (Identification numbers, coordinates, temperatures, gravities, EW(Li), A(Li) and [Fe/H] abundances, and S/N around the Li line for the observed stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/412/81/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/412/81/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/412/81/table1?GETtext/xml+votable180.050000true245.9471428-26.37491190.0055555555555555566/42955https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/412/81?format=asciiOpticaldefaultJ/MNRAS/412/81/table1Identification numbers, coordinates, temperatures, gravities, EW(Li), A(Li) and [Fe/H] abundances, and S/N around the Li line for the observed starsrecnoRecord number assigned by the VizieR team.
