cds-question@unistra.frglobular-star-clustersgiant-starschemical-abundancesThe globular cluster M15 is unique in its display of star-to-star variations in the neutron-capture elements. Comprehensive abundance surveys have been previously conducted for handfuls of M15 red giant branch (RGB) and red horizontal branch (RHB) stars. No attempt has been made to perform a single, self-consistent analysis of these stars, which exhibit a wide range in atmospheric parameters. In the current effort, a new comparative abundance derivation is presented for three RGB and six RHB members of the cluster. The analysis employs an updated version of the line transfer code MOOG, which now appropriately treats coherent, isotropic scattering.2011AJ....141..175Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/141/175CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/141/175https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/141/175http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/141/175https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/141/175https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/141/175http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/141/175GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/AJ/141/175/table1Photometry and model atmosphere parametersrecnoRecord number assigned by the VizieR team.
