Tethys and dione as sources of outward-flowing plasma in Saturn's magnetosphere

Article Abstract:

The observation of narrow injections of hot, tenuous plasma in Saturn's magnetosphere is as a result of double-peaked pitch-angle distributions which result from the transport of plasma from regions near the orbits of Dione and Tethys, supporting the idea of distinct plasma tori associated with these moons.

Solar wind dynamic pressure and electric field as the main factors controlling Saturn's aurorae

Article Abstract:

The Saturn's magnetosphere is regarded to comprise of internal and solar wind related developments. The findings indicate that its magnetosphere is robustly moved by the solar wind but the solar wind situations which move it are different from those which move the earth's magnetosphere.
