cds-question@unistra.frglobular-star-clustersline-intensitiesWe present the results of the analysis of high-resolution spectra obtained with UVES-FLAMES at the Very Large Telescope for six red giant branch stars in the outer-halo metal-poor ([Fe/H]I=-1.98 and [Fe/H]II=-1.83) Galactic globular cluster NGC 5694, which has been suggested as a possible incomer by Lee et al. based on the anomalous chemical composition of a single cluster giant. We obtain accurate abundances for a large number of elements and we find that (a)the six target stars have the same chemical composition within the uncertainties, except for Na and Al; (b) the average cluster abundance of {alpha} elements (with the only exception of Si) is nearly solar, at odds with typical halo stars and globular clusters of similar metallicity; (c) Y, Ba, La and Eu abundances are also significantly lower than in Galactic field stars and star clusters of similar metallicity. Hence, we confirm the Lee et al. classification of NGC 5694 as a cluster of extragalactic origin. We provide the first insight on the Na-O and Mg-Al anticorrelations in this cluster: all the considered stars have very similar abundance ratios for these elements, except one that has significantly lower [Na/Fe] and [Al/Fe] ratios, suggesting that some degree of early self-enrichment has occurred also in this cluster.2013MNRAS.435.3667Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/435/3667CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+AS/82/71 : Deep photometry of NGC 5694 and Terzan 8 (Ortolani+, 1990)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/435/3667https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/435/3667http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/435/3667https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/435/3667https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/435/3667http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/435/3667GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/435/3667/table1 (Fundamental parameters for target stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/435/3667/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/435/3667/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/435/3667/table1?GETtext/xml+votable180.050000true219.8853106-26.55278080.0055555555555555566/44220https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/435/3667?format=asciiOpticaldefaultJ/MNRAS/435/3667/table1Fundamental parameters for target starsrecnoRecord number assigned by the VizieR team.
