cds-question@unistra.frglobular-star-clustersgiant-starschemical-abundancesWe present aluminium abundances for a sample of about 100 red giant stars in each of the Galactic globular clusters 47 Tuc (NGC 104) and M 4 (NGC 6121). We have derived homogeneous abundances from intermediate-resolution FLAMES/GIRAFFE spectra. Aluminium abundances are from the strong doublet AlI 8772-8773{AA}, as in previous works done for giants in NGC 6752 and NGC 1851, and nitrogen abundances are extracted from a large number of features of the CN molecules by assuming a suitable carbon abundance. We added previous homogeneous abundances of O and Na and newly derived abundances of Mg and Si for our samples of 83 stars in M 4 and 116 stars in 47 Tuc to obtain the full set of elements from proton-capture reactions produced by different stellar generations in these clusters.2013A&A...550A..34Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/550/A34CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/505/117 : Abundances of red giants in 15 globular clustersJ/A+A/435/657 : Equivalent widths of 5 giants in 47 Tuc (Alves-Brito+, 2005)J/AJ/135/1551 : Abundances of stars in 47 Tuc (Koch+, 2008)J/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/ApJ/716/L166 : Lithium abundances in red giants of M4 (D'Orazi+, 2010)J/MNRAS/412/81 : Lithium abundance in M4 red giants (Mucciarelli+, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/550/A34https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/550/A34http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/550/A34https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/550/A34https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/550/A34http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/550/A34GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/550/A34/table2 (Derived abundances in 47 Tuc (table6 in html version))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/550/A34/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/550/A34/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/550/A34/table2?GETtext/xml+votable180.050000true6.0309125-71.94906670.005555555555555556Cone search capability for table J/A+A/550/A34/table3 (Derived abundances in M 4 (table7 in html version))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/550/A34/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/550/A34/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/550/A34/table3?GETtext/xml+votable180.050000true245.8742625-26.39036670.0055555555555555566/33321 42955https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/550/A34?format=asciiOpticaldefaultJ/A+A/550/A34/table2Derived abundances in 47 Tuc (table6 in html version)nMgNumber of Mg linesmeta.numberint[Mg/Fe]Abundance [Mg/Fe]log(Sun)phys.abundfloatrecnoRecord number assigned by the VizieR team.
