Abstract: Recent observations have traced the trajectories of nearby star clusters backward in time, revealing that many have converging paths and likely shared common origins. This trend spans clusters across a wide range of ages, providing evidence for sequential star formation. While stellar feedback is often invoked to explain such propagation, the dynamics of spiral arms may also compress gas and trigger new star formation. To explore this mechanism, we searched for signatures of spiral arm–induced star formation in the Feedback In Realistic Environments (FIRE) simulations. We applied the HDBSCAN clustering algorithm to identify groups of star particles with similar positions and velocities within selected regions of a simulated galaxy, and then analyzed their kinematic evolution over time. I will compare the motions of FIRE star particles to the observed trajectories of nearby stellar clusters to investigate whether spiral structure can drive sequential star formation.
