2011/1/13
We discuss the characteristics of known extremely metal-poor (EMP) stars in the Galaxy using the Stellar Abundances for Galactic Archaeology (SAGA) database (Suda et al. 2008, PASJ, 60, 1159).The anal...

We present a novel way to utilize metal-poor stars in the local, ultra-faint dwarf galaxies (UFDs) to learn about the formation process of the first galaxies. Since UFDs have much simpler star formati...
