Orbital analysis of self-consistent triaxial stellar systems
Abstract
We obtain model stellar systems that simulate two different Hubble type elliptical galaxies through cold dissipationless collapses of systems of 1,000,000 bodies. A smooth and constant gravitational potential is obtained fitting an interpolating function to the potential of each system after it reaches equilibrium. Adopting as initial conditions the positions and velocities of random samples of bodies we are then able to compute orbits and to classify them as regular and partially and fully chaotic using Lyapunov exponents. The subsequent frequency analysis of the regular orbits allows us to classify them and to find the resonant ones. Finally, we compare the orbital composition of the two systems. FULL TEXT IN SPANISH
