dc.description.abstract | We discuss the chemical composition of six giant stars of the outer Halo globular cluster NGC 5694, through the analysis of UVES@FLAMES high-resolution spectra. The cluster has an average iron content [Fe/H]=-1.83±0.01, solar-scaled [alpha /Fe] ratios and a very low Ba abundance ([Ba/Fe]=-0.71±0.06). These anomalous abundance patterns are different from those observed in other Halo globular clusters but similar to those of the metal-poor stars in typical dwarf spheroidal galaxies. These findings suggest an extra-galactic origin for NGC 5694, likely from a dwarf spheroidal galaxy.... | |
