Abstract
The gravitational instability of a dusty plasma with ion dynamics take n into account is studied. For the range of parameters relevant to pla netary rings and interstellar media: we demonstrate that the inclusion of ion dynamics cannot cause additional destabilization of a gravitat ing dusty plasma system. Streaming of the cold ions, on the other hand ; enhances the Jeans condensation of a dusty plasma. Consistency of th e results with previous work and new aspects arising owing to consider ation of ion dynamics is discussed.
