Large amplitude dust acoustic solitary waves and double layers in positively charged warm dusty plasma with nonthermal electrons

摘要

Large amplitude dust acoustic solitary waves and double layers in a nonthermal plasma consistingof positively charged dust grains, nonthermal electrons, and isothermal ions including the effect ofdust temperature have been studied using the Sagdeev potential technique by a computationalscheme. The effect of different parameters on the nature of existence of solitary waves and doublelayers has been investigated to delimit their compositional parameter space. The physicscorresponding to the computational result has been pointed out.
