Abstract
A model of a plasma consisting of electrons and two ion species with markedly different masses is considered. All the required kinetic coefficients for heavy ions are obtained for an arbitrary ratio between the densities of the ion species. The resulting complete system of equations in two-temperature magnetohydrodynamics coincides with that derived by Bobrova, Lazzaro, and Sasorov (Phys. Plasmas 12, 022102 (2005)), who, in particular, presented a full set of kinetic coefficients for electrons and light ions. The exact form of the equations and coefficients is found to be independent of the details of the description of heavy ions. On the other hand, in the cited paper, the kinetic coefficients for heavy ions were obtained for the case in which their density is not too low. In the present paper, the kinetic coefficients are obtained for heavy ions having an arbitrary density.
