cds-question@unistra.frglobular-star-clustersgiant-starschemical-abundancesWe present an abundance analysis of 101 subgiant branch (SGB) stars in the globular cluster M22. Using low-resolution FLAMES/GIRAFFE spectra we have determined abundances of the neutron-capture strontium and barium and the light element carbon. With these data we explore relationships between the observed SGB photometric split in this cluster and two stellar groups characterized by different contents of iron, slow neutron-capture process (s-process) elements, and the {alpha} element calcium, which we previously discovered in M22's red-giant stars.2012A&A...541A..15Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/541/A15CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/420/612 : Proper motions + radial velocities in M22 (Peterson+ 1994)J/PASP/107/32 : uvby-hk photometry in M22 (Anthony-Twarog+ 1995)J/ApJS/99/637 : Equivalent widths for 54 red giants (Norris+ 1995)J/A+A/373/899 : New variables in M22 globular cluster (Kaluzny+, 2001)J/MNRAS/349/1278 : BVI photometry of M22 (Monaco+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/541/A15https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/541/A15http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/541/A15https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/541/A15https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/541/A15http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/541/A15GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/541/A15/results (The dataset for the SGB stars in M22: positions, photometric data and C, Sr, Ba abundances)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/541/A15/results?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/541/A15/results?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/541/A15/results?GETtext/xml+votable180.050000true278.9384583-23.873250.0055555555555555566/28966-28967 28972-289732.367228618189496e-19 6.118840631666147e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/541/A15?format=asciidefaultJ/A+A/541/A15/resultsThe dataset for the SGB stars in M22: positions, photometric data and C, Sr, Ba abundancesRAJ2000Right ascension (J2000)pos.eq.ra;meta.mainrecnoRecord number assigned by the VizieR team.
