Dust-acoustic waves in hot dust plasma with non-thermal ions and variable dust charges



Dust-acoustic waves in hot dust plasma with non-thermal ions and variable dust charges



Xibei Shifan Daxue Xuebao (Ziran Kexue Ban) 42(5): 38-42



Using the reductive perturbation method, a modified KdV (mKdV) equation is obtained, which describes the dust acoustic waves in a hot dust plasma with dust charge variation, non-thermal distributed ions and Boltzmann distributed electrons. The properties of these solitary structures depending on the temperatures of dust grains, ions and electrons, the number of fast tons, the dust charge variation and the number densities of ions and electrons are shown in this paper numerically.
