Geometry and Kinematics of a Dancing Milky Way: Unveiling the Precession and Inclination Variation across the Galactic Plane via Open Clusters
This Letter presents a study of the geometry and motion of the Galactic disk using open clusters in the Gaia era. The findings suggest that the inclination θ _i of the Galactic disk increases gradually from the inner to the outer disk, with a shift in orientation at the Galactocentric radius of appr...
