Electrostatic waves in dusty self-gravitational flows immersed in an electron-ion plasma

Abstract

In view of various occurrences in space of bounded dusty plasmas, we consider the wave processes in an individual cylindrical dusty self-gravitational flow and in the system of dusty self-gravitating plasma streams interacting through both electric and gravitational forces. Furthermore, we include the effect of an ambient electron-ion plasma, which can play a decisive role in the interaction between dusty flows.
