Collisions as a possible case of TNOs migrations

Rok, strany: 2009, 109 - 121

We present the results of the investigation of a possible mechanism which can cause migration of objects from the Kuiper belt, mutual collisions of the objects or collisions with other populations of small solar system bodies. Analytical theories about the existence of periodical solutions in the outer variant of an averaged restricted three-body problem (the Sun — Jupiter — small body) established the existence of the periodic solutions corresponding to Keplerian osculating orbits in which the eccentricity, inclination, and semi-major axis have only periodical perturbations. The node exhibits the secular motion. Therefore, only additional forces can have influence on the motion of the Kuiper belt objects and change their orbital elements, the eccentricity, inclination and semi-major axis, such that they will have secular perturbations. In our study we used model orbits of the Classical objects of the Kuiper belt with different values of the semi-major axis and studied their orbital behaviour after the collision with bodies in orbits similar to the Kreutz cometary orbits. The change of the tangential component of their orbital velocity lies within the interval of ± 3 km s^-1. Depending on its direction, the objects will migrate to the inner or outer part of the solar system.
