Regular and chaotic dynamics of triaxial stellar systems
(Astrophysical Journal, 1998-10-20)
We use Laskar’s frequency mapping technique to study the dynamics of triaxial galaxies with central density cusps and nuclear black holes. For ensembles of 104 orbits, we numerically compute the three fundamental ...
Self-consistent gravitational chaos
(Annals of the New York Academy of Sciences, 1998-05)
The motion of stars in the gravitational potential of a triaxial galaxy is generically chaotic. However, the timescale over which the chaos
manifests itself in the orbital motion is a strong function of the degree of ...
