Ring dynamics is a research area that focuses on the study of the orbital dynamics and evolution of rings around planets and other celestial bodies. This includes the formation and stability of rings, as well as the interactions between the ring particles and the central body, moons, and other nearby objects. Ring dynamics also studies phenomena such as ring disturbances, gaps, and collisions, which can provide valuable insights into the formation and evolution of planetary systems. Studying ring dynamics can help us understand the processes that shape the structure and composition of ring systems and their role in the broader context of planetary science and astrophysics.
