- Exact traveling wave solutions of KDV equation for daws in superthermal plasma U. M. Abdelsalam M. S. Zobaer Física, Astronomía y Matemáticas waves plasmas Hydrodynamics A propagation of fully nonlinear dust-acoustic waves (DAWs) in superthermal plasma is investigated. The plasma is described by the hydrodynamic dust fluid equations with superthermal electrons and ions, where both follow a kappa distribution. The reductive perturbation method is used to analyze small but finite amplitudes nonlinear DAWs. Extended homogeneous balance method is applied to obtain the exact traveling wave solutions for the Korteweg-de Vries (KdV) equation. The solutions are numerically analyzed to study the characteristics of arbitrary and small but finite amplitudes DAWs. This study is important for understanding the nonlinear excitations that may appear in astrophysical plasma objects such as the Jupiter magnetosphere. 2018 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57171627008 https://www.redalyc.org/journal/571/57171627008/ https://www.redalyc.org/journal/571/57171627008/html/ https://www.redalyc.org/journal/571/57171627008/57171627008.epub https://www.redalyc.org/journal/571/57171627008/movil 10.14482/INDES.30.1.303.661 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Num.2 Vol.54
