Finite amplitude solitary excitations in rotating magnetized nonthermal complex (dusty) plasmas

Abstract

The nonlinear dynamics of finite amplitude dust acoustic solitary waves in rotating magnetized nonthermal plasma are investigated. For this purpose, the hydrodynamic equations for the dust grains, nonthermal ion density, and Boltzmann electron distributions together with the Poisson equation are used to derive the energy integral equation with a new Sagdeev potential. It is found that the solitary excitations strongly depend on the nonthermal ion parameters, rotational frequency, as well as dust gyrofrequency. The present investigations may be applicable to the dusty plasma situation near to the moon. © 2010 American Institute of Physics.
