Ion-acoustic solitons in plasma: an application to Saturn’s magnetosphere

摘要: Soliton formation in plasma is addressed. Nonlinear acoustic waves where the combined effects of bounded spherical geometry and transverse perturbation are dealt with, two-temperature electron studied. Using method, a Kadomtsev-Petviashvili equation (SKP) that describes ion derived. The modeled by kappa distribution function for both electrons components as found Saturn’s magnetosphere. It parameters taken into account have significant on properties nonlinear waves. model applied to magnetosphere, two temperature superthermal present. Hence, deduced three regions, namely, inner, intermediate outer We point out, this work has been motivated recent observations
