Chaos and chaotic phase mixing in cuspy triaxial potentials
Henry E. Kandrup, Christos Siopis
This paper investigates chaos and chaotic phase mixing in triaxial Dehnen potentials which have been proposed to describe realistic ellipticals. Earlier work is extended by explori…
Dynamics of Cuspy Triaxial Galaxies with a Supermassive Black Hole
Christos Siopis, Ioannis V. Sideris, Ilya V. Pogorelov +1
This talk provides a progress report on an extended collaboration which has aimed to address two basic questions, namely: Should one expect to see cuspy, triaxial galaxies in natur…
Phase space transport in cuspy triaxial potentials: Can they be used to construct self-consistent equilibria?
Christos Siopis, Henry E. Kandrup
(Abridged) This paper studies chaotic orbit ensembles evolved in triaxial generalisations of the Dehnen potential which have been proposed to model ellipticals with a strong densit…
Diffusion and scaling in escapes from two-degree-of-freedom Hamiltonian systems
Henry E. Kandrup, Christos Siopis, George Contopoulos +1
This paper summarises an investigation of the statistical properties of orbits escaping from three different two-degree-of-freedom Hamiltonian systems which exhibit global stochast…
Nonuniqueness and Structural Stability of Self-Consistent Models of Elliptical Galaxies
Christos Siopis
Schwarzschild models of a Plummer sphere were constructed and compared with analytical results to test the robustness of Schwarzschild's method and its efficiency in probing the de…
Nonuniqueness and structural stability of self-consistent models of elliptical galaxies
Christos Siopis
(Abridged:) Schwarzschild's method was used to construct equilibrium solutions to the collisionless Boltzmann equation corresponding to a Plummer sphere, which were compared with a…
