VLT/UVES Abundances of Individual Stars in the Fornax Dwarf Spheroidal Globular Clusters

International audienceWe present high resolution abundance analysis of nine stars belonging to three of the five globular clusters (GCs) of the Fornax dwarf galaxy. The spectra were taken with UVES at a resolution of 43 000. We find them to be slightly more metalpoor than what was previously calculated with other methods [1]. Fornax cluster 1 is now the most metal-poor globular cluster ever observed, with a [Fe/H] = -2.6. We find evidence of deep mixing in two stars belonging to cluster 1 and cluster 3. Also, Fornax globular clusters seem to have similar alpha/Fe ratios relative to Galactic globular clusters, though Ca and Ti may show slightly lower alpha-enhancement
