Roles of positively charged dust, ion fluid temperature, and nonthermal electrons in the formation of modified-ion-acoustic solitary and shock waves

The dusty plasma system (containing nonthermally distributed inertialess electron species, warm inertial ion and positively charged stationary dust species) is considered. basic features of subsonic supersonic modified-ion-acoustic solitary shock waves formed in such a have been investigated by the reductive perturbation method. It has shown that species play new role favor formation waves. On other hand, fluid temperature (represented parameter σ) nonthermal α) significant roles against waves, give rise to after their (σ’s α’s) certain values. also value α, as well are with negative potential. important applications results this theoretical investigation space laboratory systems pinpointed.
