ABSTRACT: The nonlinear propagation of
dust-acoustic (DA) shock waves in three-component unmagnetized dusty plasma
consisting of nonextensive electrons, Maxwellian ions and arbitrarily charged mobile
dust grain has been investigated. It is found that the presence of q-nonextensive
electrons and ions can change the nonlinear behavior of shock wave. The
standard reductive perturbation method is employed to study the basic features
(phase speed, amplitude and width) of DA shock waves (DASWs) which are
significantly modified by the presence of Maxwellian ions and nonextensive
electrons. The present investigation can be very effective for understanding
the nonlinear characteristics of the DASWs in space and laboratory dusty plasmas.
