The Composition of the Sagittarius Dwarf Spheroidal Galaxy and Implications for Nucleosynthesis and Chemical Evolution... [Pg.236]

Abstract. We have performed the chemical analysis of extragalactic carbon stars from VLT/UVES spectra. The derived individual abundances of metals and s-elements as well as the well known distance of the selected stars in the Small Magellanic Cloud and the Sagittarius dwarf galaxies permit us to test current models of stellar evolution and nucleosynthesis during the Asymptotic Giant Branch phase in low metallicity environments. [Pg.262]

In order to test the current evolution and nucleosynthesis models predicting the formation and the yields of such carbon stars, we have collected high-resolution spectra of stars located in the SMC and the Sagittarius dwarf galaxy, extragalactic systems with low average metallicity and well known distances. [Pg.262]

Chemical Abundances of RGB-Tip Stars in the Sagittarius Dwarf Spheroidal Galaxy... [Pg.270]

The Sagittarius dwarf Spheroidal galaxy (Sgr dSph) is currently disrupting under the strain of the Milky Way (MW) tidal field. The study of the Sgr chemical composition allows us to study at the same time the star formation history of a dwarf galaxy and the relevance of the hierarchical merging process for the formation of large galaxies such as the MW. [Pg.270]
