ORBITAL EVOLUTION OF DUST PARTICLES NEAR MEAN MOTION RESONANCES WITH THE EARTH

In this paper We Study the trapping of dust particles into exterior me an motion resonances with the Earth. We integrate a large number of pa rticle orbits in the context of a many-body problem taking into accoun t the effects of Poynting-Robertson and solar wind drag. Adopting a st atistical approach, we show how particles with low values of inclinati on are trapped more frequently into resonance with respect to high inc lination particles. We also present results on the dynamic evolution o f dust particles trapped in the 1/1 resonance with the Earth. Unusuall y long-lived trappings have been found.
