On the nonlinear dynamics of large scale dust-acoustic solitary waves in a superthermal bi-ion dusty ionospheric magnetoplasma

The purpose of this study is to examine the properties dust-acoustic solitary waves in a complex magnetoplasma made up negatively charged moving dust grains lower ionospheric region and inertialess electrons ions obeying Maxwell kappa distributions, respectively. In context, reductive perturbation technique carried out obtain Zakharov–Kuznetsov (ZK) equation within given framework. obtained evolution equation, i.e., ZK transformed planar dynamical system for studying qualitative behavior waves. impact important physical parameters, such as number density, ion concentration, temperature, superthermality, background magnetic field, on profile nonlinear structures numerically investigated. findings may be utilized comprehend low-frequency irregularities that are detected ionosphere.
