ELECTROSTATIC SHOCK-WAVE IN DUSTY PLASMAS

The present investigation reports the existence of a one-dimensional ( 1-D) shock wave profile for a weakly nonlinear modified acoustic-like/ dust-acoustic waves. Here, unlike in the conventional plasma systems, the dissipative effect to balance the nonlinear steepening arises self -consistently due to dust charge fluctuation dynamics in response to t he collective plasma oscillations, The possibility of other localized coherent structures like dissipative/dispersive solitons in higher-ord er solutions has been highlighted, Its implications in laboratory and space plasmas are discussed.
