Scientific paper

The motion of stars in prolate and oblate spheroidal galaxies is studied. Using a combination of Lissajous and Poincaré transformations, we introduce the set of action-angle-like variables. Then, we perturb the problem of the1:1:1 resonance motion in a spherical, homogenous galaxy, assuming the perturbing potential in the polynomial Ferrers form. We find the orbits that are periodic with respect to the radial and vertical oscillations by inspecting the equilibria of a normalized system. Imposing additional constraints, we find orbits that are periodic in all three coordinates with respect to the system that rotates with a galaxy.
