- Description:
- The present status of research on the generation of spiral patterns in the responsive density wave theory is discussed. The latter is based on a conjecture of symmetry breaking in the equations of motion of stellar orbits in differentially rotating stellar disks by an oval perturbation growing with time. Analytical approaches based on first-order epicyclic approximation as well as computer experiments are performed to investigate the consequences of this working hypothesis.
