Abstract
Linear and nonlinear processes that are related to the presence of dust and can play an important role in plasma of the Saturn’s magnetosphere are analyzed. Excitation of the lower hybrid turbulence due to the interaction of heavy ions of the Saturn’s magnetosphere with dusty plasma is described. It is demonstrated that the lower hybrid turbulence can be driven in entire region where plasma of the Saturn’s magnetosphere interacts with the charged dust. The effective collision frequency that characterizes an anomalous loss of momentum by heavy ions upon their interaction with the lower hybrid waves, along with the electric fields appearing in the system, are found. It is noted that the fields induced due to the development of the lower hybrid turbulence can influence the pattern of the electric field in the Saturn’s magnetosphere, including the field at the Enceladus orbit, despite the fact that the amplitude of the electric fields induced at the Enceladus orbit in the presence of the lower hybrid turbulence is lower than the magnitude of the electric fields at the Enceladus surface.
