We introduce a novel orbit superposition method designed to reconstruct the stellar density structure, kinematics, and chemical abundance distribution of the entire Milky Way by leveraging 6D phase-space information from its resolved stellar populations, limited by the spatial coverage of APOGEE DR17.
Key words: Galaxy: abundances / Galaxy: general / Galaxy: kinematics and dynamics / Galaxy: structure
