Solitons and shocks in e-p-i magneto-rotating plasma using Cairns distribution

Solitons and shocks formation are studied in a magnetized rotating electron-ion-positron plasma using Cairns distribution. We derive an admitted solitary wave solution KdV equation and an admitted travelling wave solution KdVB equation. We apply HPM technique on derived KdV equation and tanh-method on derived KdVB equation. It is observed thatγ=Th/TP, the ratio of electron temperature to positron temperature, andα=n0P/n0h, the ratio of number density of positrons to electrons, affect both the soliton width and amplitude. It is also found thatγ=Te/TP, α=n0P/n0h, kinematic viscosity and angular frequency affects the structure of shocks. We have compared our results with publish papers and conclude our results are good. This work may be helpful in order to study the rotating flows of magnetized plasma.
