Description
The Perseus star‑forming complex is a prime laboratory for tracing the evolution of young stars and their natal gas. Its proximity, line‑of‑sight substructure, and extensive multi‑wavelength coverage enable reconstruction of a six‑dimensional (6D) history. Using Gaia‑based SPYGLASS astrometry with APOGEE and LAMOST radial velocities, we assemble a catalogue of YSOs, and link each to local 13CO radial velocities to infer the bulk gas motion. Integrated with a 3D dust map, this provides the first steps toward reconstructing the cloud’s 6D gas field. To relate this to the older stellar population, we identify sub‑clusters with HDBSCAN and use isochronal ages to perform a dynamical traceback, connecting their evolution to the Local Bubble and Per–Tau shell. Together, these stellar–gas–dust constraints provide a unified dynamical view of how the Perseus complex assembled and how stars inherit the motions of their natal gas.
