Electrostatic Waves in a Maxwellian Dusty Plasma with Variable Charge on Dust Particles
A kinetic formulation developed to analyze wave propagation in dusty plasmas, which takes into account the variation of the charge of the dust particles due to inelastic collisions with electrons and ions, is utilized to study the propagation and damping of electrostatic waves with wave number exactly parallel to the external magnetic field and Maxwellian distributions for the electrons and ion...
متن کاملDust charge fluctuations in a magnetized dusty plasma.
Charging currents of electrons and ions to a spherical dust grain in a uniform magnetized dusty plasma have been examined. It is found that the external magnetic field reduces the charging currents, thereby decreasing the dust charge fluctuation damping of a low-frequency electrostatic wave in a dusty plasma.
متن کاملDust in Magnetized Plasmas
Overview of recent progress in studies of magnetized dusty plasmas is presented. Dust dynamic under the influence of an applied magnetic field in various types of discharges and conditions (including dust dynamic in the magnetized plasma sheath) is examined. The various dust driven mechanisms in magnetized plasma are considered and comparison experimental and theoretical data is performed. Infl...
متن کاملOrdering of dust particles in dusty plasmas under microgravity.
Structure formation of dust particles in dusty plasmas under microgravity has been simulated by the molecular dynamics method. It is shown that, at low temperatures, dust particles are organized into layered spherical shells. The number of shells is a function of the system size and the strength of screening by ambient plasma particles, while the dependency on the latter is much weaker. In the ...
متن کاملEffects of dust charge variation on electrostatic waves in dusty plasmas with temperature anisotropy
We utilize a kinetic approach to the problem of wave propagation in dusty plasmas, taking into account the variation of the charge of the dust particles due to inelastic collisions with electrons and ions. The components of the dielectric tensor are written in terms of a finite and an infinite series, containing all effects of harmonics and Larmor radius. The formulation is quite general and va...
