cds-question@unistra.frgalaxy-clustersgalaxiesphotometryccd-photometryThe spatial distribution of elemental abundances in the disc of our Galaxy gives insights both on its assembly process and subsequent evolution, and on the stellar nucleogenesis of the different elements. Gradients can be traced using several types of objects as, for instance, (young and old) stars, open clusters, HII regions, planetary nebulae. We aim to trace the radial distributions of abundances of elements produced through different nucleosynthetic channels - the {alpha}-elements O, Mg, Si, Ca and Ti, and the iron-peak elements Fe, Cr, Ni and Sc - by use of the Gaia-ESO IDR4 results for open clusters and young-field stars. From the UVES spectra of member stars, we have determined the average composition of clusters with ages >0.1Gyr. We derived statistical ages and distances of field stars. We traced the abundance gradients using the cluster and field populations and compared them with a chemo-dynamical Galactic evolutionary model. The adopted chemo-dynamical model, with the new generation of metallicity-dependent stellar yields for massive stars, is able to reproduce the observed spatial distributions of abundance ratios, in particular the abundance ratios of [O/Fe] and [Mg/Fe] in the inner disc (5kpc<R_GC_<7kpc), with their differences, that were usually poorly explained by chemical evolution models. Oxygen and magnesium are often considered to be equivalent in tracing {alpha}-element abundances and in deducing, for example, the formation timescales of different Galactic stellar populations. In addition, often [{alpha}/Fe] is computed combining several {alpha}-elements. Our results indicate, as expected, a complex and diverse nucleosynthesis of the various {alpha}-elements, in particular in the high metallicity regimes, pointing towards a different origin of these elements and highlighting the risk of considering them as a single class with common features.2017A&A...603A...2Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/603/A2CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/603/A2https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/603/A2http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/603/A2https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/603/A2https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/603/A2http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/603/A2GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/603/A2/tablea12 (Stellar parameters, radial velocities (table A1) and elemental abundances (table A2) of clusters' member stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/603/A2/tablea12?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/603/A2/tablea12?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/603/A2/tablea12?GETtext/xml+votable180.050000true100.2932917-16.46683330.005555555555555556Cone search capability for table J/A+A/603/A2/tablea34 (Stellar parameters, ages, distances, heights (table A3) and elemental abundances (table A4) of field member stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/603/A2/tablea34?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/603/A2/tablea34?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/603/A2/tablea34?GETtext/xml+votable180.050000true105.9007083-42.49952780.0055555555555555566/14336 20562 20939 21595 21913 22099 28683 28737 28739 28745 28768 28778 28968 28970 30215 30308 31812 32089 37592-37594 38302 38316 38491 38503 39332 39503 40667 40747 41466 41649 41678 42325 42337 42340 42496 42555 42604 42639 42663 42668 43034 43419 44032 44034 47780https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/603/A2?format=asciidefaultJ/A+A/603/A2/tablea12Stellar parameters, radial velocities (table A1) and elemental abundances (table A2) of clusters' member starsrecnoRecord number assigned by the VizieR team.
