Abstract

The Fornax dSpb is a nearby dwarf spheroidal galaxy with five globular clusters and a complex star formation history. It is one of the most massive dwarf spheroidal galaxies in the Local Group. Using the FLAMES/GlRAFFE spectrograph on the VLT, we have obtained high resolution (R similar to 20 000) spectra for 80 Red Giant Branch stars in the central 25' of the Fornax dSph. We present abundance ratios for some of the elements we have in our analysis, including alpha (Mg and Ca), iron-peak (Fe and Ni) and heavy (Y, Ba, Eu) elements. We compare our results with the Milky Way (MW) and our recent VLT/UVES abundance determinations of nine individual stars in Fornax globular clusters.
