Abstract
The propagation characteristics of arbitrary amplitude Dust Inertial Alfvén Solitary Wave (DIASW) has been studied in a three-component plasma consisting of magnetized cold dust, magnetized cold ions and electrons with Boltzmann distribution. The range of Mach number where solitary waves can be formed has been established analytically. To discuss the behaviors of the DIASWs, the Sagdeev potential method is used. Both rarefactive and compressive DIASWs travelling at sub and super-Alfvénic speeds are generated is this plasma model.
