Nonlinear Ion-Acoustic Waves in Degenerate Plasma with Landau Quantized Trapped Electrons

The formation of nonlinear ion-acoustic waves is studied in a degenerate magnetoplasma accounting for quantized and trapped electrons. Relying on the reductive perturbation technique, three-dimensional Zakharov–Kuznetsov (ZK) equation derived, admitting solitary wave solution with modified amplitude width parameters. stability ZK also discussed using k-expansion method. Subsequently, numerical analyses are carried out plasma parameters dense stellar system involving white dwarf stars. It has been observed that magnetic field parameter η degeneracy electrons (determined by small temperature values T) affect electric potential. critical point at which nature structure changes from compressive to rarefaction evaluated. Importantly, growth rate instability associated depends parameters, higher T tend stabilize solitons plasmas. results present study may hold significance comprehend properties propagation laboratory
