Examination of the transportation abilities of the 3:1 MMR with Jupiter

ABSTRAKT / ABSTRACT :

Resonances in the main asteroid belt play a significant role in dynamical evolution of small bodies in
the Solar system. They are capable of driving objects into near-Earth object (NEO) region as well. My
last talk was dedicated to 5:2 mean motion resonance (MMR) with Jupiter, which was believed to be rather
ineffective in delivering bodies to NEO region. This time we will deal with the transportation abilities
of the 3:1 MMR with Jupiter, which is one of the largest contributors to NEO population.  Firstly,
short-term FLI (Fast Lyapunov Indicator) maps of 3:1 MMR were computed in order to distinguish between
stable and unstable orbits. Then over 10 000 unstable particles were selected and integrated for a longer
period of time, up to 10Myr, to reveal the transportation abilities of the resonance. We are interested
in transportation to the NEO region, migration to the Sun, close encounters and collisions with the planets,
final destinations of the test particles, potentially hazardous orbits, and confrontation with the lists of
all known potentially hazardous asteroids and meteorites with pedigree. Preliminary results will be
presented.
