cds-question@unistra.fropen-star-clustersinfrared-photometryvisible-astronomybroad-band-photometryradial-velocityMilky Way open clusters are very diverse in terms of age, chemical composition, and kinematic properties. Intermediate-age and old open clusters are less common, and it is even harder to find them inside the solar Galactocentric radius, due to the high mortality rate and strong extinction inside this region. NGC 6802 is one of the inner disk open clusters (IOCs) observed by the $Gaia$-ESO survey (GES). This cluster is an important target for calibrating the abundances derived in the survey due to the kinematic and chemical homogeneity of the cluster members in open clusters. Using the measurements from $Gaia$-ESO internal data release 4 (iDR4), we identify 95 dwarf main-sequence stars as cluster members from the GIRAFFE target list, and 8 red giants as cluster members from the UVES target list. The dwarf cluster members have a median radial velocity of 13.6+/-1.9km/s, while the giant cluster members have a median radial velocity of 12.0+/-0.9km/s and a median [Fe/H] of 0.10+/-0.02dex. The color-magnitude diagram of these cluster members suggests an age of $0.9+/-0.1Gyr, with (m-M)_0_=11.4 and E(B-V)=0.86. We perform the first chemical abundance analysis of NGC 6802, including 27 element species. To gain a more general picture about IOCs, the measurements of NGC6802 are compared with those of other IOCs previously studied by GES, i.e., NGC 4815, Trumpler 20, NGC 6705, and Berkeley 81. NGC 6802 shows similar C, N, Na, and Al abundances as other IOCs. The abundance versus cluster turn-off mass for these elements in the five GES IOCs cannot firmly exclude any one of the competing nucleosynthetic models, including: standard models; models with rotation induced mixing and/or thermohaline mixing. The five GES IOCs, particularly NGC 6802, seem to have higher s-process element abundances than that of the inner disk field stars.2017A&A...601A..56Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/601/A56CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/601/A56https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/601/A56http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/601/A56https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/601/A56https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/601/A56http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/601/A56GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/601/A56/lms (Dwarf cluster members in the lower main sequence)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/601/A56/lms?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/601/A56/lms?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/601/A56/lms?GETtext/xml+votable180.050000true292.58412520.27152780.005555555555555556Cone search capability for table J/A+A/601/A56/ums (Dwarf cluster members in the upper main sequence)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/601/A56/ums?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/601/A56/ums?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/601/A56/ums?GETtext/xml+votable180.050000true292.596458320.22794440.005555555555555556Cone search capability for table J/A+A/601/A56/lmsno (Non-member dwarfs in the lower main sequence)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/601/A56/lmsno?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/601/A56/lmsno?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/601/A56/lmsno?GETtext/xml+votable180.050000true292.577791720.2430.005555555555555556Cone search capability for table J/A+A/601/A56/umsno (Non-member dwarfs in the upper main sequence)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/601/A56/umsno?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/601/A56/umsno?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/601/A56/umsno?GETtext/xml+votable180.050000true292.577541720.25777780.0055555555555555566/143363.322582951404819e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/601/A56?format=asciiOpticalInfrareddefaultJ/A+A/601/A56/lmsDwarf cluster members in the lower main sequenceSeqRow numbermeta.id;meta.mainintrecnoRecord number assigned by the VizieR team.
