Abstract

Carina is a small and faint classical dwarf spheroidal galaxy in the halo of the Milky Way with a highly episodic star formation history (e.g., Hurley-Keller et al. 1998). Using VLT/FLAMES in high resolution mode, we significantly increase the sample of stars with abundance determinations in Carina, adding to earlier work with UVES. Here we present our preliminary abundances for Fe, Mg, Ca and Ba in 23 red giant branch stars in the centre of Carina.
