Radial density, velocity and temperature profiles in a multispecies solar wind close to the coronal base - A self-consistent four-species model

A new, self-consistent four-species model is used here to demonstrate that non-Maxwellian distributions of plasma constituents in the solar wind influence the radial profiles of number density, velocity, and temperature of these species. In particular, it is shown that a simple estimate of the amoun...

Summary:A new, self-consistent four-species model is used here to demonstrate that non-Maxwellian distributions of plasma constituents in the solar wind influence the radial profiles of number density, velocity, and temperature of these species. In particular, it is shown that a simple estimate of the amount of nonthermal heating in a straightforward fashion is hampered by the fact that we do not yet know the actual character of the velocity distributions close to the coronal base.
