Kuiper Belt Objects: Dynamicak Evolution

Scientific paper

A Kuiper belt disk will have a resonant structure, arising because a subset of Kuiper belt objects, the Plutinos, are in the 3:2 mean motion resonance with Neptune. We run numerical integrations of particles originating from Plutinos to determine what percentage of particles remain in the resonance for a variety of particle and source body sizes. The dynamical evolution of the particles is followed from source to sink with Poynting-Robertson light drag, solar wind drag, radiation pressure, the Lorentz force, neutral interstellar gas drag, and the effects of planetary gravitational perturbations included. The percentage of particles in the 3:2 resonance increases with decreasing β for the cases where the source bodies are small (≤10 km), and is not significantly changed by either the addition of neutral interstellar gas drag or the Lorentz force, as long as the potential of the particles is small (U≍5 V).
