NONLINEAR ION-ACOUSTIC SOLITARY WAVES IN A DUSTY AND WEAKLY RELATIVISTIC ELECTRON-POSITRON-ION PLASMA WITH RELATIVISTIC POSITRON BEAM
The Korteweg-de Vries (KdV) equation is derived in order to investigate the existence of compressive solitons for weakly relativistic nonlinear ion-acoustic waves in an unmagnetized dusty plasma with electron inertia and relativistic positron beam. The presence of electron inertia and pressure variation has been found to cause distinct variations in the amplitude and width of compressive solitons. The investigation figures out certain specific conditions for the nonlinear ion-acoustic solitons to exist. The analysis is based on the fluid equations of motion that control the one-dimensional, collision-less warm dusty plasma. For stretching the space and time variables, different relational forms of the strength parameter are selected, resulting in various kinds of nonlinearities. Interstellar space plasma researchers and astronomers can benefit from the findings of this paper.
