Abstract :

Infrared Astronomical Satellite (IRAS) discovered three dust bands in the asteroid belt. These dust bands are believed to arise from the collision activity of asteroids. Dynamics of spherical and non-spherical particles are quite different in these regions. In this study the β values (the ratio of radiation pressure force to the solar gravity) for cylindrical particles have been evaluated. The β value for cylindrical particle strongly depends on the incident angle of radiation. The dependence of β values on the incident angle of radiation has also been formulated. Orbits in the solar radiation field are computed numerically accounting for β that varies as a function incident angle of radiation or spin of the particle.
