cds-question@unistra.fropen-star-clustersgiant-starsline-intensitiesphotometryradial-velocityWe have observed high-dispersion echelle spectra of red giant members in the five open clusters (OCs) NGC 1342, NGC 1662, NGC 1912, NGC 2354 and NGC 2447 and determined their radial velocities and chemical compositions. These are the first chemical abundance measurements for all but NGC 2447. We combined our clusters from this and previous papers with a sample drawn from the literature for which we remeasured the chemical abundances to establish a common abundance scale. With this homogeneous sample of OCs, we study the relative elemental abundances of stars in OCs in comparison with field stars as a function of age and metallicity. We find a range of mild enrichment of heavy (Ba-Eu) elements in young OC giants over field stars of the same metallicity. Our analysis supports that the youngest stellar generations in cluster might be underrepresented by the solar neighbourhood field stars.2015MNRAS.450.4301Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/450/4301CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+AS/134/301 : NGC 2354 red giants (Claria+ 1999)J/A+A/360/509 : Chemical abundances in 7 red giants (Hamdani+, 2000)J/AJ/137/4753 : EW of red giants in 4 open clusters (Jacobson+, 2009)J/AJ/139/1942 : EW of red giants in 6 open clusters (Friel+, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/450/4301https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/450/4301http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/450/4301https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/450/4301https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/450/4301http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/450/4301GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/450/4301/table2 (The journal of the observations for each of the cluster members analysed in this paper)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/450/4301/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/450/4301/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/450/4301/table2?GETtext/xml+votable180.050000true53.046791737.38206390.0055555555555555566/1302 1582 23410 39895 39901 39906 399123.322582951404819e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/450/4301?format=asciiOpticaldefaultJ/MNRAS/450/4301/table2The journal of the observations for each of the cluster members analysed in this paperrecnoRecord number assigned by the VizieR team.
