The Modulation of a Dust Ion-Acoustic Wave in a Collisional Dusty Plasma
2018
Advances in Astrophysics
The modulation instability of a dust ion-acoustic (DIA) wave in a highly collisional dusty plasma is studied theoretically. In this investigation, effects of ionization, ion loss, and electron superthermality on the DIA wave are included. By employing the standard reductive perturbation technique, a modified-nonlinear Schödinger equation (mNLSE) is developed for the evolution of the slowly varying amplitude of the DIA wave. A detailed analysis of the linear and nonlinear dispersions of the DIA
