Dust ion acoustic waves for magnetized multi-component plasma

This theoretical investigation has been done to develop a mathematical model which could used to study such plasma system in the space where electrons follow non-extensive distribution, ions are positively and negatively charged, and dust particles are also charged like ions (both positive and negative) in characteristics in the presence of an magnetic field. Using the standard reductive perturbation method and stretching coordinates, at first Zakharov-Kuznetsov (ZK) equation was derived, then extended Tanh method was used for obtaining the nonlinear wave solution of ZK equation. Finally, a computational based numerical analysis has been done where many studied characteristics are found to be exited for the nonlinear propagation of different dense astrophysical compact objects in the space where magnetic field has been found to play an equal & important role like charged ions and dust gains.

Automated summary

A mathematical model was developed to study plasma systems in space where electrons follow non-extensive distribution and ions and dust particles are charged. The study found that the magnetic field plays an important role in the nonlinear propagation of dense astrophysical objects, along with charged ions and dust particles. Numerical analysis showed that the magnetic field is equally important in this nonlinear process.
