Tripolar vortices in inhomogeneous magnetoplasmas in the presence of non-Maxwellian electron distributions

Nonlinear equations governing the characteristics of tripolar vortices (TPVs) are investigated in an inhomogeneous magnetoplasma having inertialess non-Maxwellian electrons that obey Cairns, kappa, and (r, q)-distributions. Analytical numerical solutions nonlinear presented for various possible cases. In this regard, dispersion relation drift ion-acoustic waves (IAWs) is derived, condition describing shear flow instability discussed. It realized enhancing impact aforementioned three distributions modifies size formation TPVs. found increase electron concentration regions low-phase space density leads to enhancement TPVs perturbation potential as compared effect increasing high phase density. The riveting interplay low high-energy with spiky distribution resulting novel effects on propagation vortex structures also discussed detail. present study useful understand (non)linear IAWs plasmas special reference F-region ionosphere laboratory experiments where nonthermal functions usually found.
