Oblique Propagation and Dissipation of Alfv&én Waves in Coronal Holes

Srivastava, A. K.; Dwivedi, B. N.

We investigate the effect of viscosity and magnetic diffusivity on the oblique propagation and dissipation of Alfvén waves with respect to the normal outward direction, making use of MHD equations, density, temperature and magnetic field structure in coronal holes and underlying magnetic funnels. We find reduction in the damping length scale, grou…
