cds-question@unistra.frglobular-star-clustersline-intensitiesmetallicityradial-velocityNGC 2419 is a massive outer halo Galactic globular cluster (GC) whose stars have previously been shown to have somewhat peculiar abundance patterns. We have observed seven luminous giants that are members of NGC 2419 with Keck/HIRES at reasonable signal-to-noise ratio. One of these giants is very peculiar, with an extremely low [Mg/Fe] and high [K/Fe] but normal abundances of most other elements. The abundance pattern does not match the nucleosynthetic yields of any supernova model. The other six stars show abundance ratios typical of inner halo Galactic GCs, represented here by a sample of giants in the nearby GC M30. Although our measurements show that NGC 2419 is unusual in some respects, its bulk properties do not provide compelling evidence for a difference between inner and outer halo GCs.2011ApJ...740...60Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/740/60CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/738/186 : HST and DEIMOS measurements of NGC 2419 stars (Ibata+, 2011)J/AJ/141/81 : NGC 2419 variable star population (Di Criscienzo+, 2011)J/ApJ/719/931 : Chemical evolution of the UMi dSph (Cohen+, 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/AJ/136/2259 : HST photometry of stars in NGC 2419 (Sandquist+, 2008)J/ApJ/682/1217 : Abundances in red giants in 7 globular clusters (Kirby+, 2008)J/A+A/462/L9 : Radial velocities in NGC 7099 (Scarpa+, 2007)J/PASP/117/37 : BVRI photometry in NGC 2419, Pal 4, and Pal 14 (Saha+, 2005)J/ApJ/518/262 : CCD VIc Photometry of M30 Stars (Sandquist+, 1999)J/AJ/112/1061 : BV photometry of NGC 7099 (Bergbusch 1996)http://www2.cadc-ccda.hia-iha.nrc-cnrc.gc.ca/community/STETSON/standards/NGC2419.pho : Online photometry of NGC2419 from P.
