cds-question@unistra.fropen-star-clustersgiant-starschemical-abundancesline-intensitiesWe have obtained high-resolution spectra of 32 giants in the open cluster NGC 7789 using the Wisconsin-Indiana-Yale-NOAO Hydra spectrograph. We explore differences in atmospheric parameters and elemental abundances caused by the use of the linelist developed for the Gaia-ESO Survey (GES) compared to one based on Arcturus used in our previous work. [Fe/H] values decrease when using the GES linelist instead of the Arcturus-based linelist; these differences are probably driven by systematically lower (~-0.1dex) GES surface gravities. Using the GES linelist we determine abundances for 10 elements--Fe, Mg, Si, Ca, Ti, Na, Ni, Zr, Ba, and La. We find the cluster's average metallicity [Fe/H]=0.03+/-0.07dex, in good agreement with literature values, and a lower [Mg/Fe] abundance than has been reported before for this cluster (0.11+/-0.05dex). We also find the neutron-capture element barium to be highly enhanced--[Ba/Fe]=+0.48+/-0.08--and disparate from cluster measurements of neutron-capture elements La and Zr (-0.08+/-0.05 and 0.08+/-0.08, respectively). This is in accordance with recent discoveries of supersolar Ba enhancement in young clusters along with more modest enhancement of other neutron-capture elements formed in similar environments.2015AJ....149...15Ohttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/149/15CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)J/A+A/511/A56 : Abundances of five open clusters (Pancino+, 2010)J/A+A/431/933 : Abundances of NGC 7789 evolved stars (Tautvaisiene+, 2005)J/PASP/110/1172 : NGC 7789 radial velocities (Gim+, 1998)J/PASP/110/1318 : NGC 7789 CCD VI photometry (Gim+, 1998)J/A+A/295/101 : Variable stars in field of NGC 7789 (Jahn+, 1995)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/149/15https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/149/15http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/149/15https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/149/15https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/149/15http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/149/15GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/149/15/table1 (Properties of stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/149/15/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/149/15/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/149/15/table1?GETtext/xml+votable180.050000true359.032759456.601540.005555555555555556Cone search capability for table J/AJ/149/15/spectro (Atmospheric parameters (table3) , and abundances (tables 5 and 6) of member stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/149/15/spectro?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/149/15/spectro?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/149/15/spectro?GETtext/xml+votable180.050000true358.401458356.32327780.0055555555555555566/141753.322582951404819e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/149/15?format=asciidefaultJ/AJ/149/15/table1Properties of starsrecnoRecord number assigned by the VizieR team.
