Abstract

A characteristic feature of the magnetosphere of Saturn is the presence of two types of electrons, hot and cold ones, which obey kappa distributions. Electrons, magnetospheric ions, and dust particles, which have been discovered within the Cassini mission, form a dusty plasma system in the magnetosphere of Saturn. Nonlinear periodic dust acoustic waves of arbitrary amplitude, which can propagate in the dusty magnetosphere of Saturn, are considered. The obtained results are important for the interpretation of future space observations.

土星磁层中的非线性周期性尘埃声波

土星磁层的一个特征是存在两种类型的电子，热电子和冷电子，它们服从卡帕分布。在卡西尼号任务中发现的电子、磁层离子和尘埃粒子，在土星的磁层中形成了一个尘埃等离子体系统。考虑了在土星尘埃磁层中传播的任意振幅的非线性周期性尘埃声波。获得的结果对于解释未来的空间观测具有重要意义。

期刊介绍： Plasma Physics Reports is a peer reviewed journal devoted to plasma physics. The journal covers the following topics: high-temperature plasma physics related to the problem of controlled nuclear fusion based on magnetic and inertial confinement; physics of cosmic plasma, including magnetosphere plasma, sun and stellar plasma, etc.; gas discharge plasma and plasma generated by laser and particle beams. The journal also publishes papers on such related topics as plasma electronics, generation of radiation in plasma, and plasma diagnostics. As well as other original communications, the journal publishes topical reviews and conference proceedings.
