Dust ion acoustic shock and solitary waves in a magnetized multi-component plasma with superthermal electrons

The nonlinear wave propagation in dusty plasmas has received great interest in recent decades due to its significance in interpreting some astrophysical phenomenon. Wave propagation in dust-particle plasmas is likely to differ significantly from that in normal plasmas. Depending on their time scales, several types of acoustic waves propagate in dusty plasmas. The propagation of DIA waves was investigated through a system of multi-component dusty plasma. The study shows the effect of the magnetic field and superthermal parameters on the Sagdeev potential. The Sagdeev potential falls with decreasing omega ( ci ) values and rising superthermal parameter k values. Bifurcation analysis is taken into our consideration and shown graphically under the two conditions (A > 0 ) and (A < 0). The presented theoretical work is useful in fully understanding disturbances of the electrostatic in space dusty plasmas.
