Chaotic Motion Around Stellar Objects with Octupolar Deformation: Newtonian and Post Newtonian Approaches

Javier Ramos-Caro, Framsol Lopez-Suspes, Guillermo A. Gonzalez

Regular and chaotic test particle motion in gravitational fields due to stellar bodies with quadrupolar and octupolar deformation are studied using Poincare surfaces of section. In…
