cds-question@unistra.frglobular-star-clustersvisible-astronomybroad-band-photometrychemical-abundancesInformation on globular clusters (GC) formation mechanisms can be gathered by studying the chemical signature of the multiple populations that compose these stellar systems. In particular, we investigate the anti-correlations among O, Na, Al, and Mg to explore the influence of cluster mass and environment on GCs in the Milky Way and in extragalactic systems. We present here the results obtained on NGC 6139, which, on the basis of its horizontal branch morphology, has been proposed to be dominated by first-generation stars. In our extensive study based on high-resolution spectroscopy, the first for this cluster, we found a metallicity of [Fe/H]=-1.579+/-0.015+/-0.058 (rms=0.040dex, 45 bona fide member stars) on the UVES scale defined by our group. The stars in NGC 6139 show a chemical pattern normal for GCs, with a rather extended Na-O (and Mg-Al) anticorrelation. NGC 6139 behaves as expected from its mass and contains a large portion (about two thirds) of second-generation stars.2015A&A...583A..69Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/583/A69CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/PAZh/22/764 : Photometry of the globular cluster NGC 6139 (Samus+, 1996)J/A+A/540/A27 : Spectroscopy in Galactic globular clusters (Saviane+, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/583/A69https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/583/A69http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/583/A69https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/583/A69https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/583/A69http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/583/A69GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/583/A69/phottab (Photometric catalogue)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/583/A69/phottab?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/583/A69/phottab?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/583/A69/phottab?GETtext/xml+votable180.050000true246.689975-38.620791670.005555555555555556Cone search capability for table J/A+A/583/A69/tablea2 (Information on non-member stars on the basis of RV or metallicity, all observed with GIRAFFE)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/583/A69/tablea2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/583/A69/tablea2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/583/A69/tablea2?GETtext/xml+votable180.050000true246.8560417-38.811850.005555555555555556Cone search capability for table J/A+A/583/A69/tablea1 (Information on the member stars observed)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/583/A69/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/583/A69/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/583/A69/tablea1?GETtext/xml+votable180.050000true246.9159167-38.83834720.0055555555555555566/427613.322582951404819e-19 4.920466254354166e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/583/A69?format=asciiOpticaldefaultJ/A+A/583/A69/phottabPhotometric cataloguerecnoRecord number assigned by the VizieR team.
