Parameters of dusty plasma in Saturn's magnetosphere

The parameters of dusty plasmas of Saturn’s magnetosphere at different distances from the planet are considered. Special attention is given to the parameters near the moon Enceladus. The influence of the photoelectric effect caused by the interaction of dust component of Saturn’s magnetospheric plasma with solar radiation on its parameters is discussed. It is demonstrated that due to the photoelectric effect, even though far away from the Sun, there may be situations where dust particles can gain a positive charge. Conditions under which dust particles could carry a positive charge were defined. A qualitative method was suggested for identifying scenarios when dust particles carry either positive or negative charges.
