cds-question@unistra.frchemical-abundancesglobular-star-clustersgiant-starsWe use abundances of Ca, O, Na, and Al from high-resolution UVES spectra of 200 red giants in 17 globular clusters (GCs) to investigate the correlation found by Lee et al. (2009Icar..199..413C) between chemical enrichment from SNII and star-to-star variations in light elements in GC stars. We find that (1) the [Ca/H] variations between first and second generation stars are tiny in most GCs (~0.02-0.03dex, comparable with typical observational errors). In addition, (2) using a large sample of red giants in M4 (NGC 6121) with abundances from UVES spectra from Marino et al. (2008, Cat. J/A+A/490/625), we find that Ca and Fe abundances in the two populations of Na-poor and Na-rich stars are identical.2010ApJ...712L..21Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/712/L21CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/505/139 : Abundances of red giants in 17 globular clusters (Carretta+,J/A+A/503/545 : Equivalent widths of Li, Na, Fe, Ca in NGC 6397 (Lind+, 2009)J/A+A/490/625 : Abundances of NGC 6121 red giants (Marino+, 2008)J/A+A/490/777 : Abundances of Population II stars in NGC 6397 (Lind+, 2008)J/A+A/486/941 : Abundances in M71 (NGC 6838) (Alves-Brito+, 2008)J/A+A/464/939 : Abundances of red giants in NGC 6218 (Carretta+, 2007)J/A+A/464/927 : Abundances of red giants in NGC 6752 (Carretta+, 2007)J/AJ/131/1766 : Abundances and equivalent widths in NGC 2808 (Carretta, 2006)J/A+A/434/235 : Abundances of BHB stars in NGC 1904 (Fabbian+, 2005)J/A+A/440/901 : Reddening and metallicity of NGC 6752 (Gratton, 2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/712/L21https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/712/L21http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/712/L21https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/712/L21https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/712/L21http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/712/L21GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/712/L21/table1 (The [Ca/Fe] and [Ca/H] ratios for individual stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/712/L21/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/712/L21/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/712/L21/table1?GETtext/xml+votable180.050000true6.07032083-72.1970750.005555555555555556Cone search capability for table J/ApJ/712/L21/table2 (Mean [Ca/Fe], [Ca/H] ratios and internal errors for the 17 globular clusters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/712/L21/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/712/L21/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/712/L21/table2?GETtext/xml+votable180.050000true6.0223292-72.08144440.0055555555555555566/12405 12943 16647 21017 24843 30769 31019 31115 31416 31417 33321 37294 37636 38465 42076 42955 47125 47168 47970 47971 48434 48440https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/712/L21?format=asciiOpticaldefaultJ/ApJ/712/L21/table1The [Ca/Fe] and [Ca/H] ratios for individual starsrecnoRecord number assigned by the VizieR team.
