cds-question@unistra.frglobular-star-clustersgiant-starschemical-abundancesWe present chemical abundances in three red giants and two turnoff (TO) stars in the metal-poor Galactic globular cluster (GC) NGC 6397 based on spectroscopy obtained with the Magellan Inamori Kyocera Echelle high-resolution spectrograph on the Magellan 6.5m Clay telescope. Our results are based on a line-by-line differential abundance analysis relative to the well-studied red giant Arcturus and the Galactic halo field star HIP 66815.2011AJ....142...63Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/142/63CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/287/769 : UV photometry of NGC 6397 (Burgarella+ 1994)J/PASP/108/682 : Low-Mass Stars in Outer Field in NGC 6397 (Mould+, 1996)J/A+AS/122/1 : BV photometry of variables in NGC 6397 (Kaluzny, 1997)J/AJ/119/1225 : Omega Cen and NGC 6397 Stroemgren photometry (Hughes+, 2000)J/AJ/120/3111 : Stromgren photometry of NGC 6397 (Anthony-Twarog+, 2000)J/A+A/425/509 : VI photometry of NGC 6397 (Andreuzzi+, 2004)J/A+A/490/777 : Abundances of Population II stars in NGC 6397 (Lind+, 2008)J/AJ/135/2141 : F814W+F606W photometry of NGC 6397 faint stars (Richer+, 2008)J/A+A/503/545 : Equivalent widths of Li, Na, Fe, Ca in NGC 6397 (Lind+, 2009)J/A+A/505/L13 : Lithium in globular NGC 6397 (Gonzalez Hernandez+, 2009)J/ApJ/709/241 : NGC 6397 X-rays sources characterisation (Bogdanov+, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/142/63https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/142/63http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/142/63https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/142/63https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/142/63http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/142/63GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/142/63/stars (Details of observations, target properties and atmospheric parameters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/142/63/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/142/63/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/142/63/stars?GETtext/xml+votable180.050000true265.084167-53.70050.0055555555555555566/42076https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/142/63?format=asciiOpticaldefaultJ/AJ/142/63/starsDetails of observations, target properties and atmospheric parametersrecnoRecord number assigned by the VizieR team.
