Effect of Ion-Parallel Viscosity on the Propagation of Alfven Surface Waves

Abstract

The paper analyzes the damping of the Alfven surface waves via ion parallel viscosity at a single magnetic interface. The dispersion relation is obtained and characteristics curves are drawn for the real and imaginary phase speeds. The modes thus obtained are two damped Alfven modes propagating in a way such that when one mode dies new mode appears after a certain propagation gap. The results are applicable for the situation in solar wind at AU for values obtained from the spacecraft data.
