Dynamic behavior of macroparticles in two-components dusty plasma induced by solar radiation under microgravity conditions.

摘要

The results of experimental investigation of the dynamic behavior of macroparticles charged by photoemission under conditions of microgravity are presented. The experimental data have been obtained for bronze particles illuminated by solar radiation (space station "Mir") The distribution of velocities, temperatures, charge as well as friction coefficient and diffusion constants have been found. The analysis of the results obtained has shown that the polarization effects of oppositely charges may appreciably influence the transport processes in two components dusty plasma, consisting of positive ions and electrons.
