Abstract

The two-dimensional model of the solar wind-local interstellar medium interaction developed by Baranov & Malama (1993, J. Geophys. Res., 98, 15 157) is improved by taking into account the dynamical effect of anomalous cosmic rays. The cosmic rays are treated as a massless diffusive fluid. It is shown that the termination shock shifts further away from the Sun in this case and the post-shock temperature of the thermal plasma decreases. The magnitude of the shift depends on the value of the energy-averaged spatial diffusion coefficient. The number density of energetic neutral hydrogen originating in the shocked solar wind is generally lower in the case of the cosmic-ray-modified termination shock.
