| Abstract: | The dynamics of the formation of ordered structures of macroparticles charged by photoemission under the action of solar radiation
under microgravitational conditions without the use of electrostatic traps to confine the particles is studied experimentally
and theoretically. The working conditions needed for the formation of structures of charged macroparticles are chosen as a
result of a numerical solution of the problem posed, the particle charges and the interparticle interaction parameter are
determined, and the characteristic times specifying the dynamics of the formation of an ordered system of macroparticles are
calculated. The behavior of an ensemble of macroparticles under the effect of solar radiation is observed experimentally on
board the Mir space station. An analysis and comparison of the results of the experimental and theoretical investigations
permit drawing a conclusion regarding the possibility of the existences of extended ordered formations of macroparticles charged
by photoemission under microgravitational conditions.
