Dust-ion acoustic solitary waves are investigated in this multispecies plasma model, which includes negative mobile dusts, non-thermal ions, and Boltzmann electrons, using a reductive perturbative technique to derive the relevant Korteweg-de Vries (KdV) equation. The amount of dust charges contained in a dust particle (Zd), as well as the streaming speeds of mobile dusts (ud0) and ions (ui0), are found to play a crucial role in the formation of dust-ion acoustic compressive and rarefactive KdV solitons. In a short range of Zd separated by some asymptotic lines, some initial streaming of dust (ud0) is discovered to be crucial for both compressive and rarefactive KdV solitons. Compressive and rarefactive KdV solitons of either concave or convex characteristics are also proven to represent the existence of low dust charges and decreased ion streaming. The amplitudes of the rarefactive KdV solitons move from higher to lower as the streaming of mobile dusts increases, indicating a convex nature for this plasma model. The number of dust charges contained in a dust particle (Zd) dramatically changes the amplitudes of the compressive and rarefactive KdV solitons, according to a comprehensive theoretical analysis.
The study's major goal is to figure out how Zd and the streaming speeds of mobile dusts (ud0) and ions (ui0) in a multispecies plasma made up of negative mobile dusts, non-thermal ions, and Boltzmann electrons generate dust-ion acoustic compressive and rarefactive KdV solitons.Author(S) Details
