N - body Simulations with Cohesion in Dense Planetary Rings
Title of Dissertation: N-body Simulations with Cohesion in Dense Planetary Rings Randall Patrick Perrine, Doctor of Philosophy, 2011 Dissertation directed by: Professor Derek C. Richardson Department of Astronomy This dissertation is primarily focused on exploring whether weak cohesion among icy particles in Saturn’s dense rings is consistent with observations—and if so, what limits can be plac...
متن کاملN-body simulations of cohesion in dense planetary rings: A study of cohesion parameters
We present results from a large suite of simulations of Saturn’s dense A and B rings using a new model of particle sticking in local simulations (Perrine, R.P., Richardson, D.C., Scheeres, D.J. [2011]. Icarus 212, 719– 735). In this model, colliding particles can be incorporated into or help fragment rigid aggregations on the basis of certain user-specified parameters that can represent van der...
متن کاملTree code simulations of planetary rings
A tree code method that incorporates a local shearing disc model and fourth-order integration algorithm is applied to the problem of planetary rings, with particular emphasis on the dynamics of Saturn's B ring. The new code, described in detail elsewhere, allows for particle self-gravity, a distribution of particle sizes, and surface friction (particle spin). Important changes made to the origi...
متن کاملN-body simulations of resonance rings in galactic disks
We have studied the formation of rings in the disks of galaxies by using two-dimensional N-body simulations where the gas component is modelled as dissipatively colliding test particles. Our results support the standard hypothesis that ring formation occurs when gas is driven to resonances by the gravitational torque of a rotating stellar bar. When the bar is absent, a weaker oval-shaped mode o...
متن کاملGravitational N -Body Simulations
This book discusses in detail all the relevant numerical methods for the classical N body problem. It demonstrates how to develop clear and elegant algorithms for models of gravitational systems and explains the fundamental methematical tools needed to describe the dynamics of a large number of mutually attractive particles. Particular attention is given to the techniques needed to model astrop...
