Chemical Abundances of New Member Stars in the Tucana II Dwarf Galaxy
We present chemical abundance measurements for seven stars with metallicities ranging from Fe/H] =-3.3 to [Fe/H] =-2.4 in the Tucana II ultra-faint dwarf galaxy (UFD), based on high-resolution spectra obtained with the MIKE spectrograph on the 6.5 m Magellan-Clay Telescope. For three stars, we present detailed chemical abundances for the first time. Of those, two stars are newly discovered members of Tucana II and were selected as probable members from deep narrowband photometry of the Tucana...[Show more]
