Brief Summary: ''... The impact-generated dust contributions of the other E ring satellites is estimated and significant differences in the dust ejection efficiency by two projectile families—the E ring particles (ERPs) and the interplanetary dust particles (IDPs) is found. Together with the Enceladus south-pole source, the ERP impacts play a crucial role in the inner region, whereas the IDP impacts dominate the particle production in the outer E ring, possibly accounting for its large radial extent. ...''
Cassini Dust Measurements at Enceladus and Implications for the Origin of the E Ring
Brief Summary: ''In this study, we investigate the micron-sized dust particle distrubution around Enceladus, a moon in Saturn's E-ring with cryo-vulcanic activity. Realistic simulations are compared with data collected during Cassini’s close flyby of Enceladus on 14 July 2005 by the High Rate Detector of the Cosmic Dust Analyzer. The dust impact rate peaked about 1 minute before the closest approach of the spacecraft to the moon. This asymmetric signature is consistent with a locally enhanced dust production in the south polar region of Enceladus...''
