The Effects of Moons on Saturn’s Ring System

چکیده

The ring system of Saturn is a complex interaction between numerous particles, moons, and Saturn. A program was created to simulate the different aspects of the ring system and to study the effects of moons on the orbiting particles. Simply by considering both the force of gravity on each particle and collisions between particles, gaps formed at eight different resonant positions. I also studied the effects of collision elasticity and found that less elastic collisions cause the gaps to form more quickly. Furthermore, the effects of shepherding were studied by embedding an orbiting moon in the ring particles. By varying the mass ratio of Saturn to the moon, it was found that the smaller the mass ratio between Saturn and the moon, the larger the gap cleared in the ring and the larger the width of the ringlet formed in the center of the gap. It was also observed that resonances interior to the moon controlled the interior edge of gaps while resonances exterior to the moon controlled the exterior edge of the gaps.

Gravitoelectrodynamics in Saturn’s F ring: encounters with Prometheus and Pandora

The dynamics of Saturn’s F ring have been a matter of curiosity ever since Voyagers 1 and 2 sent back pictures of the ring’s unusual features. Some of these images showed three distinct ringlets with the outer two displaying a kinked and braided appearance. Many models have been proposed to explain the braiding seen in these images; most of these invoke perturbations caused by the shepherding m...

Density Waves Observed by Cassini Stellar Occultations as Probes of Saturn’s

Introduction: Spiral density waves are launched in Saturn’s rings at locations of orbital resonances with nearby moons. These waves provide a means of probing fundamental properties of the ring such as mass, thickness, and collision velocities [1, 2]. These properties constrain models of the origin and evolution of Saturn’s rings. Density waves are collisionally damped, and the damping therefor...

Numerical results on a simple model for the confinement of Saturn’s F ring

In this paper we discuss a simple model for the confinement of Saturn’s F ring and present some preliminary numerical results. The model involves the gravitational interaction of independent test particles with Saturn, including its second zonal harmonic, the shepherd moons Prometheus and Pandora, and Titan, the largest of Saturn’s satellites. We perform accurate long-time integrations (3.2× 10...

Diamagnetic expulsion as a possible cause of the origin and stability of saturn’s rings

To date, the origin and evolution of Saturn’s rings have not been consistently explained. There are several hypotheses concerning the origin of Saturn’s rings, which can be summarized as follows.1 (a) The ring particles can be collision-generated debris from current moons. (b) A satellite in the Roche Zone was destroyed by a passing comet. (c) A massive comet was tidally disrupted during a clos...
