cds-question@unistra.frmilky-way-galaxyglobular-star-clustersgiant-starsradial-velocitychemical-abundanceseffective-temperatureWe present radial velocities and chemical abundances for red giant branch stars in the Galactic bulge globular clusters NGC6342 and NGC6366. The velocities and abundances are based on measurements of high-resolution (R>~20000) spectra obtained with the MMT-Hectochelle and WIYN-Hydra spectrographs. We find that NGC6342 has a heliocentric radial velocity of +112.5km/s ({sigma}=8.6km/s), NGC6366 has a heliocentric radial velocity of -122.3km/s ({sigma}=1.5km/s), and both clusters have nearly identical metallicities ([Fe/H]~-0.55). NGC6366 shows evidence of a moderately extended O-Na anti-correlation, but more data are needed for NGC6342 to determine if this cluster also exhibits the typical O-Na relation likely found in all other Galactic globular clusters. The two clusters are distinguished from similar metallicity field stars as having larger [Na/Fe] spreads and enhanced [La/Fe] ratios, but we find that NGC6342 and NGC6366 display {alpha} and Fe-peak element abundance patterns that are typical of other metal-rich ([Fe/H]>-1) inner Galaxy clusters. However, the median [La/Fe] abundance may vary from cluster-to-cluster.2016AJ....152...21Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/152/21CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)VII/202 : Globular Clusters in the Milky Way (Harris, 1997)J/A+A/584/A59 : Proper motions and membership in NGC 6366 (Sariya+, 2015)J/ApJ/810/148 : Red giant abundances in NGC 2808 (Carretta, 2015)J/AJ/148/67 : Abundances of 156 bulge red giants (Johnson+, 2014)J/A+A/549/A147 : Abundances of microlensed Bulge dwarf stars (Bensby+, 2013)J/ApJ/765/157 : Abundances of red giants in the Gal. bulge (Johnson+, 2013)J/A+A/540/A27 : Spectroscopy in Galactic globular clusters (Saviane+, 2012)J/ApJ/749/175 : Abundances for stars in Plaut's window (Johnson+, 2012)J/ApJ/732/108 : Abundances of 92 giants in Plaut's window (Johnson+, 2011)J/A+A/534/A80 : [Fe/H] of bulge clump giants in Baade's window (Hill+, 2011)J/A+A/533/A134 : Abundances of microlensed stars in the Bulge (Bensby+, 2011)J/A+A/530/A54 : Abundances of 650 bulge red giants (Gonzalez+, 2011)J/A+A/513/A35 : Abundances of Galactic red giants (Alves-Brito+, 2010)J/A+A/505/139 : Abundances of red giants in 17 GCs (Carretta+, 2009)J/A+A/505/117 : Abundances of red giants in 15 GCs (Carretta+, 2009)J/other/RMxAA/44.365 : New variable stars in NGC 6366 (Arellano Ferro+, 2008)J/A+A/464/967 : Abundances of red giants in NGC 6388 (Carretta+, 2007)J/A+A/464/953 : Abundances of red giants in NGC 6441 (Gratton+, 2007)J/A+A/455/271 : Abundances of red giants in NGC 6441 (Gratton+, 2006)J/A+A/450/105 : Properties of 153 Galactic globular clusters (Bica+, 2006)J/MNRAS/351/1204 : IR Photometry of 10 Galactic GCs (Valenti+, 2004)J/ApJ/590/797 : Parameters of galactic GCs (Van Den Bregh+, 2003)J/AJ/106/604 : Study of globular cluster NGC 6366 (Harris 1993)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/152/21https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/152/21http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/152/21https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/152/21https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/152/21http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/152/21GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/152/21/stars (Coordinates, photometry, and velocities in NGC 6342 (table1), and in NGC 6366 (table2))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/152/21/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/152/21/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/152/21/stars?GETtext/xml+votable180.050000true259.91911111-19.617743060.0055555555555555565/7322 6/30995 309988.650015785639275e-20 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/152/21?format=asciidefaultJ/AJ/152/21/starsCoordinates, photometry, and velocities in NGC 6342 (table1), and in NGC 6366 (table2)SimbadNameSimbad column added by the CDSmeta.idcharf_2MASS[h] Flag on 2MASS (h=star observed with both Hectochelle and Hydra instruments)meta.codecharrecnoRecord number assigned by the VizieR team.
