Temperature bistability of charged dust particle in plasma
  By computer numerical simulation of heating of a dust conducting particle in homogeneous plasma it was shown that depending on initial temperature of a particle both heating and cooling were possible with formation of two different quasi-stable conditions - temperature bistability. The "hot" condition corresponds to positive charge of the particle and "cold" condition corresponds to negative charge. The stability of the "cold" state is provided by radiation losses. The method of experimental observation of the effect was proposed.
