We use Schwarzschild's orbit superposition method to build self-consistent models of elliptical galaxies with scale-free potentials. Our exhaustive study of all physical shapes and central densities for galaxies with scale-free potentials establishes a relationship between the presence of chaos and self-consistency. The extent and the onset of chaos is studied by varying parameters of the model which are believed to be its inducers, such as the steepness of the central density cusp, flatness… 


Bifurcations of Periodic Orbits in Axisymmetric Scalefree Potentials a
This study suggests that stable period‐three orbits generally arise de novo in stable and unstable pairs via a turning‐point bifurcation, and not through a bifURcation from the thin tube at a 120° rotation angle.
