Description
Summary:In this article, the propagation of ion-acoustic shock and periodic waves along with their dynamical analysis around the supercritical values is studied in a (1 + 1)-dimensional collisionless negative ions plasma system comprising of inertia SF 6 − with mass m − i and temperature T − i, inertia K+ with mass m + i and temperature T + i and inertialess non-extensive distributed electrons. By considering the appropriate starching coordinates and expansion of perturbation quantities, the Burgers-type equation with quartic nonlinearity is derived. Using the traveling wave transformation, a planar dynamical system is formed. The phase portrait is drawn and the associated nonlinear waves are analyzed. The research presented could be beneficial for understanding and forecasting localized electrostatic disturbances in the F- and D-layers of Earth's ionosphere as well as for guiding future experimental investigations in plasma laboratories.
