Higher-order corrections to solitary waves in a non-isothermal relativistic plasma with cold ions and two-temperature electrons

A critical analysis of nonlinear waves in a non-isothermal relativistic plasma is performed using reductive perturbation theory. The plasma is assumed to contain two-temperature electrons. Higher-order corrections to the solitary wave are also computed, and the variations of the profile with respect to v/c, the two temperatures of the electrons, and the parameters b_l, and b_n characterising the non-isothermal nature are depicted graphically and com-pared with previous results.
