N-body simulations of the Self-Confinement of Viscous Self-Gravitating Narrow Eccentric Planetary Ringlets
Joseph M. Hahn, Douglas P. Hamilton, Thomas Rimlinger +1
Narrow eccentric planetary ringlets have sharp edges, sizable eccentricity gradients, and a confinement mechanism that prevents radial spreading due to ring viscosity. Most propose…
The Shape of Saturn's Huygens Ringlet Viewed by Cassini ISS
Joseph N. Spitale, Joseph M. Hahn
A new model for the shape of the prominent eccentric ringlet in the gap exterior to Saturn's B-ring is developed based on Cassini imaging observations taken over about 8 years. Unl…
An N-body Integrator for Gravitating Planetary Rings, and the Outer Edge of Saturn's B Ring
Joseph M. Hahn, Joseph N. Spitale
A new symplectic N-body integrator is introduced, one designed to calculate the global 360 degree evolution of a self-gravitating planetary ring that is in orbit about an oblate pl…
Diagnosing Circumstellar Debris Disks
Joseph M. Hahn
(Abridged) A numerical model of a circumstellar debris disk is developed and applied to observations of the circumstellar dust orbiting beta Pictoris. The model accounts for the ra…
Dynamics of the Sharp Edges of Broad Planetary Rings
Joseph M. Hahn, Joseph N. Spitale, Carolyn C. Porco
(Abridged) The following describes a model of a broad planetary ring whose sharp edge is confined by a satellite's m^th Lindblad resonance (LR). This model uses a streamline formal…
The Secular Evolution of a Close Ring-Satellite System: The Excitation of Spiral Density Waves at a Nearby Gap Edge
Joseph M. Hahn
The Lagrange planetary equations are used to study to secular evolution of a small, eccentric satellite that orbits within a narrow gap in a broad, self-gravitating planetary ring.…
