| Description | The effect of neutral-gas friction on Alfvén surface waves propagating along an infinitely conducting viscous plasma–vacuum interface has been investigated. A dispersion relation is obtained for such waves. For different values of the neutral-gas friction parameter $S=ν_{c}$/ω (where $ν_{c}$ is the collisional frequency between two components of the composite plasma), the variations of the real and imaginary parts $k_{r}$ and $k_{i}$ of the wavenumber k with the viscosity parameter $v_{p}$= μ_{l}ω/ρ_{01}v^{2}$_{A1}$ (where $μ_{l}$ and $ρ_{01}$ are the coefficient of viscosity and the density of plasma media 1) are shown graphically. It is concluded that a three-mode structure of Alfvén surface waves results flowing to neutral-gas friction. It is suggested that our results are useful for both laboratory and astrophysical plasmas (e.g. photospheres, chromospheres and cool interstellar clouds). |
