cds-question@unistra.frglobular-star-clusterspopulation-ii-starschemical-abundancesOur FLAMES survey of Na-O anticorrelation in globular clusters (GCs) is extended to NGC 4833, a metal-poor GC with a long blue tail on the horizontal branch (HB). We present the abundance analysis (Na, O, Mg, Al, Si, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Y, Ba, La, Nd)for 78 red giants based on UVES and GIRAFFE spectra acquired at the ESO-VLT. NGC 4833 has [Fe/H]=-2.015+/-0.004+/-0.084dex (rms=0.014dex) from 12 stars observed with UVES; the iron abundance is homogeneous at better than 6%. The Na-O anticorrelation in NGC 4833 is quite extended, as expected from the high temperatures reached by stars on the HB, and NGC 4833 contains a conspicuous fraction of stars with extreme [O/Na] ratios. Large star-to-star variations are seen also for Mg, which spans a range of more than 0.5dex in this GC. Depletions in Mg are correlated to the abundances of O and anti-correlated with Na, Al, and Si abundances. This pattern suggests the action of nuclear processing at unusually high temperatures, producing the extreme chemistry observed in the stellar generations of NGC 4833. This extreme changes are also seen in giants of the much more massive GCs M 54 and omega Cen, and our conclusion is that NGC 4833 has probably lost a conpicuous fraction of its original mass due to bulge shocking, as also indicated by its orbit.2014A&A...564A..60Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/564/A60CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/455/271 : NGC 6441 red giant abundances (Gratton+, 2006)J/A+A/464/927 : NGC 6752 red giant abundances (Carretta+, 2007)J/A+A/464/939 : NGC 6218 red giant abundances (Carretta+, 2007)J/A+A/464/953 : NGC 6441 red giant abundances (Gratton+, 2007)J/A+A/464/967 : NGC 6388 red giant abundances (Carretta+, 2007)J/A+A/505/117 : 15 globular clusters red giant abundances (Carretta+, 009)J/A+A/505/139 : 17 globular clusters red giant abundances (Carretta+, 2009)J/A+A/533/A69 : Spectroscopy of 124 RGB stars (Carretta+, 2011)J/A+A/550/A34 : M4 and 47 Tuc red giant abundances (Carretta+, 2013)J/A+A/520/A95 : M54 and Sgr dSph red giant abundances (Carretta+, 2010)J/A+A/557/A138 : NGC362: red giant abundances (Carretta+ 2013)J/A+AS/109/479 : BV Photometry in for NGC 4833 (Samus+, 1995)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/564/A60https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/564/A60http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/564/A60https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/564/A60https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/564/A60http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/564/A60GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/564/A60/stars (All results on the observed stars: postions abd velocities (table2), adopted atmospheric parameters and [Fe/H] (table6), abundances (tables 7--11))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/564/A60/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/564/A60/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/564/A60/stars?GETtext/xml+votable180.050000true194.7731625-70.949963890.0055555555555555566/415223.322582951404819e-19 4.920466254354166e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/564/A60?format=asciiOpticaldefaultJ/A+A/564/A60/starsAll results on the observed stars: postions abd velocities (table2), adopted atmospheric parameters and [Fe/H] (table6), abundances (tables 7--11)nFeINumber of FeI linesmeta.numberintnCa?
