Abstract:
The dispersion relation of Alfvén Surface Waves propagating along the moving viscous plasma–vacuum interface has been derived and solved numerically. The plasma layer is below while the upper layer is assumed to be vacuum. The layer of plasma is assumed to be moving parallel to the direction of the background magnetic field. This interface supports two modes of viscous-damped Alfvén Surface Waves when the plasma is static. However, when the flow is introduced, new modes start evolving in addition to the existing modes and the damping due to viscosity increases.
