Spectral analysis of stellar orbits in a tidally induced bar

Spectral analysis of stellar orbits in a tidally induced bar

Grzegorz Gajda, Ewa L. Łokas and E. Athanassoula

Using numerical analysis of fundamental frequencies we study the orbital structure of a tidally induced bar formed in a simulated dwarf galaxy orbiting a Milky Way-like host. We find that only about 10% of stars have frequencies compatible with x1 orbits, the classical periodic orbits in a barred potential. The rest of the stars follows box orbits parallel to the bar, with varying degree of elongation.
