Dust Acoustic and Dust Ion Acoustic Nonlinear Structures : Theory and Experiments

Dust acoustic and dust ion acoustic nonlinear structures in complex (dusty) plasmas are described. The emphasis is given to the new results. We describe the dust acoustic bow shock formed in the interaction of the solar wind with cometary dusty coma. We discuss the possibility of observation of shocks related to the dust charging process in active rocket experiments, which involve the release of some gaseous substance in near-Earth space, as well as the laboratory experiments modeling active those. We present an explanation of the experiments in rf plasma discharge where phase transition was occurred during dust acoustic shock propagation.
