Oblique Solitary Waves in a Five Component Plasma with Pair Ions

[摘要] We investigate the influence of ions of different masses on oblique solitary waves in five component plasma consisting of positively and negatively charged heavier ions (dust), hydrogen ions and hotter and colder electrons. Of these, the heavier ions and colder photo-electrons are of commentary origin while the other two are of solar origin; the electrons being described by kappa distributions. The K-dV equation is derived and different attributes of the soliton such as amplitude and width are plotted for parameters relevant to that of comet Halley. We find that heavier ions strongly influence the amplitude and width of the solitary waves.
