Abstract:

In this talk, I will introduce our recent work on the chemodynamical properties of the Milky Way bulge. Specifically, we use Gaia DR3 and the Auriga simulations to investigate the metallicity and kinematic properties of different stellar structures, including the Splash. Furthermore, we perform an orbital decomposition of stellar orbits in the bulge from the Auriga simulations to dissect various orbital families, enabling us to explore their metallicity-related morphology and kinematic properties.
