Investigation of Substructures of the Inner Halo Using the StarGO Algorithm with APOGEE DR17

Investigation of Substructures of the Inner Halo Using the StarGO Algorithm with APOGEE DR17

We applied the Stars’ Galactic Origin algorithm in 7D space (i.e., [Fe/H], [Mg/Fe], [Al/Fe], L _z ,  J _r ,  J _z ,  E ) to analyze stars in the inner halo with APOGEE DR17. We identified some known substructures, including Gaia-Sausage/Enceladus, Sagittarius stream (Sgr), LMS-1 (Wukong), Thamnos, t...
