Dust Streaming Effect on Dust Acoustic Solitary Wave in Magnetized Dust-Ion Plasmas

摘要

The dust acoustic solitary structures in the presence of dust streaming are obtained through Sagdeev's pseudopotential approach in magnetized dustion plasmas. It is found that dust streaming plays a destructive role in the formation of dust acoustic solitary structures. However, the wave amplitude increases with the increase in the Mach number and obliqueness of the wave in the presence of contant dust streaming along a uniform external magnetic field. The numerical results are applied to Saturn's F-rings for illustrative purposes.
