Inner Lindblad resonance in galaxies. Nonlinear theory. I.
Abstract
In the reported investigation use is made of the action-angle variables employed by Kalnajs (1971) in the study of galactic resonant problems. The Hamiltonian corresponding to a spiral galaxy is expressed with the aid of action-angle variables. A third-order epicyclic theory is used and the spiral perturbation relations are developed. Attention is given to resonant orbits, the resonant form of the Hamiltonian, the periodic orbits near resonance, and questions of applications.
