Stationary state of thermostated inelastic hard spheres

We consider a fluid composed of inelastic hard spheres moving in a thermostat modelled by a hard sphere gas. The losses of energy due to inelastic collisions are balanced by the energy transfer via elastic collisions from the thermostat particles. The resulting stationary state is analysed within the Boltzmann kinetic theory, A numerical iterative method permits to study the nature of deviations from the Gaussian state, Some analytic results are obtained for a one-dimensional g reserved, system.
