J/A+A/506/729       Abundances in globular cluster Pal 3           (Koch+, 2009)

All quiet in the outer halo: chemical abundances in the globular cluster Pal 3. Koch A., Cote P., McWilliam A. <Astron. Astrophys. 506, 729 (2009)> =2009A&A...506..729K
ADC_Keywords: Clusters, globular ; Abundances ; Stars, giant Keywords: stars: abundances - Galaxy: abundances - Galaxy: evolution - Galaxy: halo - globular clusters: individual: Pal 3 Abstract: Chemical abundances of 25 alpha-, iron peak-, and neutron-capture elements in the remote (R=90kpc) outer halo globular cluster have been determined for 4 red giants observed with the Magellan/MIKE spectrograph and from integrated spectra of 19 stars obtained with the Keck/HIRES instrument. The resulting abundance ratios show that Pal 3 is very similar to globular clusters of the inner halo and very dissimilar from dwarf spheroidal galaxy stars. Its neutron capture element ratios are compatible with a pure r-process enrichment.
