Plasma Emission Modifications and Instabilities Induced by the Presence of Growing Dust Particles

Formation of dust particles in a plasma can strongly change its properties due to electron attachment on dust surface. An easy way to detect dust formation is to analyze modifications of the plasma emission. In this paper, changes in the plasma emission are related to the growth of dust particles. We particularly show that dust formation induces low-frequency plasma instabilities. Another interesting induced effect is the formation of an enhanced emission region which is dust free and usually named ldquovoidrdquo.
