\label{eqn:jouleratio2}  \frac{\Gamma_B}{\Gamma_r} = \frac{1}{16 \pi} \frac{\eta}{\kappa} \, .  \end{equation}  Therefore, for magneto-gravity waves,  joule damping cannot exceed thermal damping unless the magnetic diffusivity is significantly larger than the thermal diffusivity. In stellar interiors (and our RGB models), the magnetic diffusivity is typically orders of magnitude smaller than the thermal diffusivity. Therefore joule damping can safely be ignored. We note that the same result occurs if we use the Alfven wave dispersion relation in the first line of equation \ref{eqn:jouleratio}, so joule damping is also unimportant for Alfven waves.
