Small amplitude ion-acoustic solitary waves in a four-component magneto- rotating plasma with a modified Cairns-Tsallis distribution

Abstract The small amplitude ion-acoustic solitary waves in the magneto-rotating plasma consisting of cold fluid ions, hot positrons, and two-temperature electrons (cold electrons) are investigated when obey a modified Cairns-Tsallis distribution. By using reductive perturbation method, we derive Korteweg–de Vries equation obtain wave solutions. dependences solutions on nonextensive q -parameter, nonthermal α -parameter physical quantities analyzed numerically. We show significant effects etc waves.
