Abstract

It has recently been suggested that the peculiar cluster Pal 1 is associated to the Canis Major dwarf galaxy, which existence is still at the center of a debate. Our first measurement of the cluster’s chemical abundance ratios allows us to examine this association and to advance further in the clarification of Pal 1 possible origin.
