Title: Effect of Streaming Negative Ions on Dust Acoustic Wave Propagation in Complex Plasma

Abstract

The role of streaming negative ions on the dust acoustic wave (DAW) propagation has been investigated based on orbit motion limited (OML) theory of dust grain charging. The complex plasma being assumed as composed of Boltzmanian electrons, inertial positive ions, streaming negative ions and the variable charge dust grains. Dust charge is assumed to be fluctuating. It is found that the dust acoustic wave becomes unstable when ratio of the thermal velocity with the streaming velocity of negative ions crosses some threshold value.
