cds-question@unistra.fropen-star-clusterschemical-abundanceseffective-temperatureradial-velocityTrumpler 23 is a moderately populated, intermediate-age open cluster within the solar circle at a R_GC_~6kpc. It is in a crowded field very close to the Galactic plane and the color-magnitude diagram shows significant field contamination and possible differential reddening; it is a relatively understudied cluster for these reasons, but its location makes it a key object for determining Galactic abundance distributions. New data from the Gaia-ESO Survey enable the first ever radial velocity and spectroscopic metallicity measurements for this cluster. We aim to use velocities to isolate cluster members, providing more leverage for determining cluster parameters. Gaia-ESO Survey data for 167 potential members have yielded radial velocity measurements, which were used to determine the systemic velocity of the cluster and membership of individual stars. Atmospheric parameters were also used as a check on membership when available. Literature photometry was used to re-determine cluster parameters based on radial velocity member stars only; theoretical isochrones are fit in the V, V-I diagram. Cluster abundance measurements of ten radial-velocity member stars with high-resolution spectroscopy are presented for 24 elements. These abundances have been compared to local disk stars, and where possible placed within the context of literature gradient studies. We find Trumpler 23 to have an age of 0.80+/-0.10Gyr, significant differential reddening with an estimated mean cluster E(V-I) of 1.02^+0.14^_-0.09_, and an apparent distance modulus of 14.15+/-0.20. We find an average cluster metallicity of [Fe/H]=0.14+/-0.03dex, a solar [{alpha}/Fe] abundance, and notably subsolar [s-process/Fe] abundances.2017A&A...598A..68Ohttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/598/A68CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/598/A68https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/598/A68http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/598/A68https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/598/A68https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/598/A68http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/598/A68GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/598/A68/tablea1 (Parameters for Trumpler 23 radial velocity members with GIRAFFE data)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/598/A68/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/598/A68/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/598/A68/tablea1?GETtext/xml+votable180.050000true240.2377083-53.55672220.005555555555555556Cone search capability for table J/A+A/598/A68/tablea2 (Parameters for Trumpler 23 radial velocity non-members with GIRAFFE data)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/598/A68/tablea2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/598/A68/tablea2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/598/A68/tablea2?GETtext/xml+votable180.050000true240.243125-53.49861110.005555555555555556Cone search capability for table J/A+A/598/A68/tablea3 (Parameters for Trumpler 23 targets with UVES data)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/598/A68/tablea3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/598/A68/tablea3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/598/A68/tablea3?GETtext/xml+votable180.050000true240.2153333-53.53369440.0055555555555555566/424963.322582951404819e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/598/A68?format=asciiOpticaldefaultJ/A+A/598/A68/tablea1Parameters for Trumpler 23 radial velocity members with GIRAFFE datarecnoRecord number assigned by the VizieR team.
