cds-question@unistra.frglobular-star-clusterspopulation-ii-starschemical-abundancesline-intensitiesWe present the abundance analysis of stars from the tip of the red giant branch (RGB) to below the RGB bump in the globular cluster NGC 2808 based on high-resolution echelle spectra. We derive abundances of Al, {alpha}-process elements (SiI, CaI, TiI, and TiII), and Fe-group elements (ScII, VI, CrI, CrII, MnI, CoI, and NiI). Apart from Mg being somewhat reduced, likely because it has been depleted at the expense of Al in the MgAl cycle, the other {alpha}-element ratios show the overabundance typical of halo stars of similar metallicity.2006AJ....131.1766Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/131/1766CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/413/343 : RGB stars in NGC 2808 (Cacciari+, 2004)J/A+A/417/597 : Radial velocities in 4 globular clusters (Recio-Blanco+, 2004)J/A+AS/84/59 : Photometry of NGC 2808 (Ferraro+, 1990)J/ApJ/562/368 : UV photometry in NGC 2808 (Brown+, 2001)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/131/1766https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/131/1766http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/131/1766https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/131/1766https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/131/1766http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/131/1766GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/131/1766/table1 (Adopted atmospheric parameters and Fe abundances)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/131/1766/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/131/1766/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/131/1766/table1?GETtext/xml+votable180.050000true138.1906556-64.784830.0055555555555555566/37057 37294https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/131/1766?format=asciiOpticaldefaultJ/AJ/131/1766/table1Adopted atmospheric parameters and Fe abundancesrecnoRecord number assigned by the VizieR team.
