Abstract:
Chemical abundances of 25 elements, which include α-, iron peak-,
and neutron-capture elements, in the outer halo globular cluster
Palomar 14 have been determined for the nine red giants observed with
the FLAMES/UVES spectrograph. The abundance pattern of Pal 14 is
similar to the inner halo GCs, halo field stars, and GCs of recognized
extragalactic origin, but differs from what is customarily found in
dSphs field stars. The abundance properties of Pal 14 as well as those
of the other outer halo GCs are thus compatible with an accretion
origin from dSphs. The neutron-capture elements show an r-process
signature.
