cds-question@unistra.frgalaxiesgiant-starschemical-abundancesWe report for the first time on the chemical composition of the halo cluster NGC 5897 (R_{sun}_=12.5kpc), based on chemical abundance ratios for 27 {alpha}-, iron-peak, and neutron-capture elements in seven red giants. From our high-resolution, high signal-to-noise spectra obtained with theMagellan/MIKE spectrograph, we find a mean iron abundance from the neutral species of [Fe/H]=-2.04+/-0.01(stat.)+/-0.15(sys.), which is more metal-poor than implied by previous photometric and low-resolution spectroscopic studies. NGC 5897 is {alpha}-enhanced (to 0.34+/-0.01dex) and shows Fe-peak element ratios typical of other (metal-poor) halo globular clusters (GCs) with no overall, significant abundance spreads in iron nor in any other heavy element.2014A&A...565A..23Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/565/A23CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/565/A23https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/565/A23http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/565/A23https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/565/A23https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/565/A23http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/565/A23GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/565/A23/table1 (Properties of the targeted stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/565/A23/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/565/A23/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/565/A23/table1?GETtext/xml+votable180.050000true229.3752917-21.03578060.0055555555555555566/444273.322582951404819e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/565/A23?format=asciiOpticaldefaultJ/A+A/565/A23/table1Properties of the targeted starsSimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
