\label{fig:Prop2}  {\bf Panel A: Wave speeds in the the stellar model shown in Figures \ref{fig:Prop} and and \ref{Fig:Struc}.} We have plotted the sound speed, $v_s$, gravity wave radial group velocity, $v_{g,r}$ (for $\omega=2 \pi \nu_{\rm max}$), and Alfven speed, $v_A$. Waves travel at a group velocity of $v_s$, $v_{g,r}$, and $v_A$ for acoustic, gravity, and Alfven waves, respectively. {\bf Panel B:} Radial wave number, $k_r$, for a wave with $\omega=2 \pi \nu_{\rm max}$, as a function of radius. We have plotted the wavenumbers of acoustic waves (p-waves), fast magneto-gravity waves (fast-waves), slow magneto-gravity waves (slow-waves), Alfven Alfv\'en  waves (a-waves), and the evanescent part of the wave (ev-wave). The dashed blue line shows the wavenumber for gravity waves (g-waves) in the absence of a magnetic field. The solid black line shows the {\bf maximum} of $r^{-1}$ or $H^{-1}$ (where $H$ is a pressure scale height).
