| Abstract: |
Chemical abundances for twenty one elements are presented for four red
giants in the anomalous outer halo globular cluster Palomar 1. The
mean metallicity, [Fe/H] = –0.60 ± 0.01, is high for a
globular cluster so far from the Galactic center. In addition, its
[α/Fe] and neutron capture abundances seem to indicate an
origin in a dwarf galaxy, although it is not definitively associated
with any known streams. |
