AB: On approach to Saturn, during the first half of 2004, the Cosmic Dust Analyzer (CDA) onboard Cassini detected streams of small, fast dust particles thought to emanate from the Saturnian system. In this study, using magnetic field data obtained by the Cassini magnetometer (MAG) and solar wind velocity data obtained by Cassini Plasma Spectometer (CAPS), we simulate the trajectories of dust particles ejected from the Saturnian system as they propagate through the interplanetary medium where they are strongly influenced by the interplanetary magnetic field. By comparing the simulation results with data obtained by CDA we attempt to determine whether Saturn is indeed the point of origin and further characterize the nature of the dust particles detected onboard Cassini.
