Exploring Asymmetric Substructures of the Outer Disk Based on the Conjugate Angle of the Radial Action
We use the conjugate angle of radial action ( θ _R ), the best representation of the orbital phase, to explore the “midplane,” “north branch,” “south branch,” and “Monoceros area” disk structures that were previously revealed in the LAMOST K giants. The former three substructures, identified by thei...
