Abstract

Plane, periodic stellar orbits in the spiral gravitational field of the Galaxy superimposed on the axisymmetric background potential are studied in the epicyclic approximation. The superposition of such orbits is illustrated to demonstrate the response of the stellar system to an imposed spiral density perturbation.
