Abstract

Methods of description of ion–acoustic shock waves in dusty plasma are presented. A new type of dust ion–acoustic shock waves related to anomalous dissipation is described. The main dissipative processes related to charging of dust particles, absorption of ions by dust particles, Coulomb collisions between ions and dust particles, and Landau damping are analyzed. Proposed methods of theoretical analysis enable explaining all major specific features of dust ion–acoustic shock waves observed in the laboratory experiments. The shock waves of this type are present in the near-Earth plasma and the universe. Their investigation is possible in active ionospheric experiments of the Fluxus type. Important astrophysical problems in which the appearance of shock waves under consideration should be taken into consideration are the shock waves of supernovas, evolution of Local Interstellar medium, etc.

实验室，电离层和天体物理等离子中的尘埃离子声波

摘要

介绍了描述尘土等离子体中离子声冲击波的方法。描述了一种与异常耗散有关的新型粉尘离子声波。分析了与尘埃颗粒带电，尘埃颗粒对离子的吸收，离子与尘埃颗粒之间的库仑碰撞以及Landau阻尼有关的主要耗散过程。提出的理论分析方法可以解释在实验室实验中观察到的粉尘离子声冲击波的所有主要特定特征。这种冲击波存在于近地等离子体和宇宙中。在活跃的电离层类型电离层实验中，他们的研究是可能的。需要考虑所考虑的冲击波出现的重要天体物理问题是超新星的冲击波，
