Abstract
In this article, we consider a dense astrophysical plasma consisting of predominantly electrons, positrons, and ions under the action of the magnetic field of a star or planet. We have derived the Korteweg-de Vries-Burgers (KdV)-Burgers equations using the Poincaré-Lighthill-Kuo (PLK) method and obtained shock and solitary wave solutions for magnetoacoustic waves. We have further studied the mutual interaction of such stationary formations and the breakdown mechanism. The possibility of a rogue wave-like structure is also discussed. We have used a newly designed code to study the time evolution of wave-wave interaction and the breakdown mechanism. The results will be helpful to interpret magnetoacoustic wave formations in solar corona, or other stellar entities and can help in understanding the study of inhomogeneous plasmas in laboratory and fusion reactors.
