摘要: Properties of dust-acoustic solitary waves in a warm dusty plasma are analyzed by using the hydrodynamic model for massive dust grains, electrons, ions, and streaming ion beam. For this purpose, Korteweg-de Vries (KdV) equation first-order perturbed potential linear inhomogeneous KdV-type second-order have been derived their analytical solutions presented. In order to show characteristics influenced parameters, relevant numerical analysis KdV equations obtained. The waves, as predicted here, may be associated with nonlinear structures caused interaction polar jets interstellar medium, which is known Herbig-Haro objects.
