Abstract

Explores the scenario that the large random velocity (approx 5 km/s) among the asteroids is the result of dynamical interaction between the original population of the parent asteroids in near-circular orbits with some large planetesimals (JZB) scattered from the accretion zone of Jupiter. The statistical property of such a gravitational scattering process is evaluated using a Monte Carlo method. It is found that a few tens of JZB with individual masses reaching 3 X 1027 g would be needed to provide the necessary orbital velocity dispersion. -Author
