cds-question@unistra.frgalaxiesglobular-star-clustersapparent-magnitudemetallicityspectroscopyline-intensitiesDetailed chemical abundances are presented for seven M31 outer halo globular clusters (with projected distances from M31 greater than 30 kpc), as derived from high-resolution integrated light spectra taken with the Hobby-Eberly Telescope. Five of these clusters were recently discovered in the Pan-Andromeda Archaeological Survey (PAndAS) - this paper presents the first determinations of integrated Fe, Na, Mg, Ca, Ti, Ni, Ba, and Eu abundances for these clusters. Four of the target clusters (PA06, PA53, PA54, and PA56) are metal poor ([Fe/H]< -1.5), {alpha}-enhanced (though they are possibly less {alpha}-enhanced than Milky Way stars at the 1{sigma} level), and show signs of star-to-star Na and Mg variations. The other three globular clusters (H10, H23, and PA17) are more metal rich, with metallicities ranging from [Fe/H]=-1.4 to -0.9. While H23 is chemically similar to Milky Way field stars, Milky Way globular clusters, and other M31 clusters, H10 and PA17, have moderately low [Ca/Fe], compared to Milky Way field stars and clusters. Additionally, PA17's high [Mg/Ca] and [Ba/Eu] ratios are distinct from Milky Way stars, and are in better agreement with the stars and clusters in the Large Magellanic Cloud. None of the clusters studied here can be conclusively linked to any of the identified streams from PAndAS; however, based on their locations, kinematics, metallicities, and detailed abundances, the most metal-rich PAndAS clusters H23 and PA17 may be associated with the progenitor of the Giant Stellar Stream, H10 may be associated with the SW cloud, and PA53 and PA56 may be associated with the eastern cloud.2015MNRAS.448.1314Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/448/1314CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/143 : Revised Bologna Catalog of M31 clusters, V.5 (Galleti+ 2012)J/AJ/122/2458 : M31 globular clusters from HST (Barmby+, 2001)J/AJ/124/234 : M31 outer halo UBVRI photometry and metallicityJ/AJ/133/2764 : M31 globular clusters structural parameters (Barmby+, 2007)J/A+A/508/1285 : Metallicity estimates of M31 globular clustersJ/A+A/544/A155 : HST photometry of M31 globular clusters (Federici+, 2012)J/A+A/549/A60 : Ages and [Fe/H] of M31 globular clusters (Cezario+, 2013)J/ApJ/769/10 : Spectroscopy of M31 globular clusters (Jacoby+, 2013)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/448/1314https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/448/1314http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/448/1314https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/448/1314https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/448/1314http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/448/1314GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/448/1314/table1 (Properties of the target PAndAS clusters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/448/1314/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/448/1314/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/448/1314/table1?GETtext/xml+votable180.050000true8.9987535.6843330.0055555555555555566/2598 2640 2646 2656 2694 2729https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/448/1314?format=asciiOpticaldefaultJ/MNRAS/448/1314/table1Properties of the target PAndAS clustersSimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
