cds-question@unistra.frstellar-evolutionary-modelssupernovaestellar-mass-losschemical-abundancesopen-star-clustersWe have computed with a fine time grid the evolution of the elemental abundances of He, C, N and O ejected by young (t<20Myr) and massive (M=10^6^M_{sun}_) coeval stellar cluster with a Salpeter initial mass function (IMF) over a wide range of initial abundances. Our computations incorporate the mass loss from massive stars (M>=30M_{sun}_) during their wind phase including the Wolf-Rayet phase and the ejecta from the core-collapse supernovae. We find that during the Wolf-Rayet phase (t<5Myr) the cluster ejecta composition suddenly becomes vastly overabundant in N for all initial abundances and in He, C and O for initial abundances higher than one-fifth of the solar. The C and O abundances in the cluster ejecta can reach over 50 times the solar value with important consequences for the chemical and hydrodynamical evolution of the surrounding interstellar medium.2012MNRAS.425.1696Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/425/1696CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/425/1696https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/425/1696http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/425/1696https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/425/1696https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/425/1696http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/425/1696GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/MNRAS/425/1696/table1Basic information for 7 stellar masses (12, 15, 20, 30, 40, 60, 100) and 6 metallicites (0.0001, 0.0004, 0.004, 0.008, 0.02, 0.05)recnoRecord number assigned by the VizieR team.
