The ion acoustic solitary waves in the four-component complex plasma with a Cairns-Tsallis distribution

• Ion acoustic solitary waves in the four-component complex plasma with Cairns-Tsallis distribution are studied. Conditions of to exist Numerical analyses for depend on nonextensive and nonthermal parameters made. We study ion consisting cold inertial ions, positrons, hot (two-temperature) electrons, where electrons positrons a have different parameters. Base hydrodynamic equations Sagdeev pseudo-potential theory, we derive conditions plasma, such as pseudo- potential, normalized electrostatic lower upper limits Mach number, compressive/rarefactive wave. show that, according present study, wave solutions only if Maxwellian two-temperature same made depending distribution.
