HR-GO. II. Chemical Abundances of Low-E Retrograde Dynamically Tagged Groups: Revealing Thamnos as a Very Metal-poor Substructure
Milky Way halo substructures identified in dynamical space are known to suffer from contamination from the Milky Way in situ stars, which makes their accreted origins uncertain. We present detailed chemical abundances of 35 stars belonging to two sets of dynamically tagged groups, Rg8 and Rg9, to investigate their accreted nature. Both groups are
