Resonant instabilities mediated by drag and electrostatic interactions in laboratory and astrophysical dusty plasmas

Dusty plasmas are known to support a diverse range of instabilities, including both generalizations standard plasma instabilities and ones caused by effects specific dusty systems. It has been recently demonstrated that novel broad class streaming termed resonant drag (RDIs), can be attributed particular resonance phenomenon, manifested defective eigenvalues the linearized dust/fluid system. In this work, it is phenomenon not unique RDIs used as framework understand wider instabilities. Particular attention given filamentary ionization instability seen in laboratory two-stream instability. shown that, due commonalities underlying physics between dust-ion-acoustic acoustic RDI, these should relevant strongly overlapping regimes astrophysical plasmas. proposed similar overlap experimental accessibility modes (and instability) allows for possibility investigation complex astrophysically dynamics.
