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 species, and positively charged stationary dust species) is considered. The basic features of subsonic and supersonic modified-ion-acoustic solitary and shock waves formed in such a dusty pla...

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