Statistical mechanics of collisionless orbits. I. Origin of central cusps in dark-matter halos

We present an equilibrium statistical mechanical theory of collisionless self-gravitational systems with isotropic velocity distributions.
Origin and Dynamics of the Mutually Inclined Orbits of Upsilon Andromedae c and d

We evaluate the orbital evolution and several plausible origins scenarios for the mutually inclined orbits of υ And c and d. These two planets have orbital ele-ments that oscillate with large amplitud...
Asymptotic Orbits in Barred Spiral Galaxies

2010/12/28
We study the formation of the spiral structure of barred spiral galaxies, using an $N$-body model. The evolution of this $N$-body model in the adiabatic approximation maintains a strong spiral pattern...
Statistical mechanics of collisionless orbits. III. Comparison with N-body simulations

We compare the DARKexp differential energy distribution, N(E) \propto \exp(\phi_0-E)-1, obtained from statistical mechanical considerations, to the results of N-body simulations of dark matter halos.

In this paper, we present the density, \rho, velocity dispersion, \sigma, and \rho/\sigma^3 profiles of isotropic systems which have the energy distribution, N(E)\propto[\exp(\phi_0-E)-1], derived in ...
