cds-question@unistra.frglobular-star-clustersdwarf-starsgiant-starsline-intensitieseffective-temperatureMost globular clusters are believed to host a single stellar population. They can thus be considered a good place to study the Spite plateau and to search for possible evolutionary modifications of the Li content. We want to determine the Li content of subgiant (SG) and main sequence (MS) stars of the old, metal-poor globular cluster NGC 6397. This work was aimed not only at studying possible Li abundance variations but also to investigate the cosmological Li discrepancy.2009A&A...505L..13Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/505/L13CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/287/769 : UV photometry of NGC 6397 (Burgarella+ 1994)J/PASP/106/404 : NGC 6535 BV CCD photometry (Sarajedini, 1994)J/ApJS/99/637 : Equivalent widths for 54 red giants (Norris+ 1995)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/A+A/425/509 : VI photometry of NGC 6397 (Andreuzzi+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/505/L13https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/505/L13http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/505/L13https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/505/L13https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/505/L13http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/505/L13GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/505/L13/table2 (Effective temperature, Equivalent Width and Li abundances in stars of NGC 6397)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/505/L13/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/505/L13/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/505/L13/table2?GETtext/xml+votable180.050000true265.1280417-53.79441670.0055555555555555566/42076https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/505/L13?format=asciiOpticaldefaultJ/A+A/505/L13/table2Effective temperature, Equivalent Width and Li abundances in stars of NGC 6397recnoRecord number assigned by the VizieR team.
