Self-consistent Gravitational Chaos
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 central concentration of the galaxy. Here, chaotic diffusion rates are presented for orbits in triaxial models with a range of central density slopes and nuclear black-hole masses....
متن کاملBuilding Self-Consistent Triaxial Galaxy Models Using Schwarzschild’s Method
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...
متن کاملSelf-consistent Massive Disks in Triaxial Dark Matter Halos
Galactic disks in triaxial dark matter halos become deformed by the elliptical potential in the plane of the disk in such a way as to counteract the halo ellipticity. We develop a technique to calculate the equilibrium configuration of such a disk in the combined disk-halo potential, which is based on the method of Jog but accounts for the radial variation in both the halo potential and the dis...
متن کاملSelf-consistent models of triaxial galaxies in MOND gravity
The Bekenstein-Milgrom gravity theory with a modified Poisson equation is tested here for the existence of triaxial equilibrium solutions. Using the nonnegative least square method, we show that self-consistent triaxial galaxies exist for baryonic models with a mild density cusp ρ ∼ Σ r . Self-consistency is achieved for a wide range of central concentrations, Σ ∼ 10 − 1000M⊙pc , representing l...
متن کاملPhase space transport in cuspy triaxial potentials : Can they be used to construct self - consistent equilibria ?
This paper focuses on the statistical properties of chaotic orbit ensembles evolved in triaxial generalisations of the Dehnen potential which have been proposed recently to model realistic ellipticals that have a strong density cusp and manifest significant deviations from axisymmetry. Allowance is made for a possible supermassive black hole, as well as low amplitude friction, noise, and period...
