Zagorodny (Bogolyubov Institute for Theoretical Physics, NAS Ukraine, Metrologichna 14-b,03680, Kyiv, Ukraine) | The stationary distribution function of Brownian particles in a nonequilibrium dusty plasma is calculated with regard to electron and ion absorption by grains. The distribution is shown to be considerably different from the distribution function of ordinary Brownian particles in thermal equilibrium. A criterion for the grain-structure formation in a nonequilibrium dusty plasma is derived. Key words: Brownian motion, Langevine equation, Fokker-Planck equation, nonequilibrium
