Model of the Linearized Collision Operator for Plasmas with Temperature Anisotropy

A model kinetic operator is proposed, describing the relaxation of the first sixteen hydrodynamic moments of a two-component plasma with temperature anisotropy with respect to an external magnetic field. The analytical expression given for the model, taking into account only density, velocity, and temperature relaxation, is more exact than a corresponding Bhatnagar-Gross-Krook model.
