THE CHEMICAL EVOLUTION OF THE BOÖTES I ULTRA-FAINT DWARF GALAXY
We present chemical abundance measurements of two metal-poor red giant stars in the ultra-faint dwarf galaxy Boötes I, based on Magellan/MIKE high-resolution spectra. For Boo-980, with Fe/H = - 3.1, we present the first elemental abundance measurements, while Boo-127, with Fe/H = - 2.0, shows abunda...
