Dust acoustic wave in a strongly magnetized pair-dust plasma
The existence of the dust acoustic wave (DAW) in a strongly magnetized electron-positron (pair)dust plasma is demonstrated. In the DAW, the restoring force comes from the pressure of inertialess electrons and positrons, and the dust mass provides the inertia. The waves could be of interest in astrophysical settings such as the supernovae and pulsars, as well as in cluster explosions by intense ...
متن کاملDust in Flowing Magnetized Plasma
Plasma flows occur in almost every laboratory device and interactions of flowing plasmas with near-wall impurities and/or dust significantly affects the efficiency and lifetime of such devices. The charged dust inside the magnetized flowing plasma moves primarily under the influence of the plasma drag and electric forces. Here, the charge on the dust, plasma potential, and plasma density are ca...
متن کاملInvestigation of Dust-Ion Acoustic Waves in a Magnetized Collisional Dusty Plasma with Kappa Distribution Function for Electrons
The propagation of arbitrary amplitude dust ion acoustic waves (DIAWs) in a magnetized collisional dusty plasma including hot electrons, with kappa velocity distribution for electrons, warm ions and dust particles has been studied. In the presence of immobile massive dust particulates, DIAWs have been investigated through the Sagdeev pseudo-potential method. It is demonstrated that the amplitud...
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 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.
