The Origin of r -process Enhanced Metal-poor Halo Stars In Now-destroyed Ultra-faint Dwarf Galaxies
The highly r-process-enhanced (r-II) metal-poor halo stars we observe today could play a key role in understanding early ultra-faint dwarf galaxies (UFDs), the smallest building blocks of the Milky Way. If a significant fraction of metal-poor r-II halo stars originated in the UFDs that merged to hel...
