Abstract

In this paper we examine the question how turbulent wave-particle processes modify on dayside the MHD obstacle boundary for those nonmagnetic bodies which have ionosphere. Inside the magnetosphere of nonmagnetic bodies, there is always a central part, a magnetic cavity, where the solar wind magnetic field normally can not penetrate. The ionosphere of the body, residing inside this cavity, can penetrate through the cavity boundary, forming a region populated by planetary/cometary ions and shocked solar wind. This region is called mantle. As experimental evidences show, it exists around Mars, Venus and comets. In the mantle the cold planetary ions form a beam in the decelerated solar wind, exciting waves in the low-hybrid frequency region. The waves accelerate electrons, and also transmit momenta to cold heavy ions, causing a friction like interaction between the solar wind and planetary ions. It is likely that the diffusive processes in the mantle defines the most important physical characteristics of this region.
