cds-question@unistra.frmilky-way-galaxyglobular-star-clusterschemical-abundancesGlobular clusters are considered key objects for understanding the formation and evolution of the Milky Way. In this sense, the characterisation of their chemical and orbital parameters can provide constraints on chemical evolution models of the Galaxy. We use the heavy element abundances of globular clusters to trace their overall behaviour in the Galaxy, with the aim to analyse potential relations between the hot H-burning and s-process elements. We measured the content of CuI and s- and r-process elements (YII, BaII, LaII, and EuII) in a sample of 210 giant stars in 18 galactic globular clusters from high-quality UVES spectra. These clusters span a broad metallicity range and the sample is the largest that has been uniformly analysed to date, with respect to heavy elements in globular clusters. The Cu abundances did not show a considerable spread in the sample, nor any correlation with Na, indicating that the Na nucleosynthesis process does not affect the Cu abundance. Most GCs closely follow the Cu, Y, Ba, La, and Eu field stars' distribution, revealing a similar chemical evolution. The Y abundances in mid-metallicity regime GCs (-1.10dex<[Fe/H]<-1.80dex) display a mildly significant correlation with the Na abundance, which ought to be further investigated. Finally, we do not find any significant difference between the n-capture abundances among GCs with either Galactic and extragalactic origins.2024A&A...685A..10Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/685/A10CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/505/139 : Abundances of red giants in 17 globular clustersJ/A+A/600/A118 : Abundances of red giant stars in NGC6093 (M80)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/685/A10https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/685/A10http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/685/A10https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/685/A10https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/685/A10http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/685/A10GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/685/A10/table2 (Abundance of Cu, Y, Ba, La, and Eu for a sample of 210 stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/685/A10/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/685/A10/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/685/A10/table2?GETtext/xml+votable180.050000true325.1013983-23.1608950.0055555555555555566/12405 12943 16647 21017 24843 25873 30769 31019 31115 31416-31417 33321 37294 37636 38465 42076 42955 47125 47168 47970-47971 48434 48440https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/685/A10?format=asciidefaultJ/A+A/685/A10/table2Abundance of Cu, Y, Ba, La, and Eu for a sample of 210 starsSimbadNameSimbad column added by the CDSmeta.idcharnullablerecnoRecord number assigned by the VizieR team.
