%The striking agreement between our calculation of suppressed dipole mode visibility and the observations of \citet{Mosser_2011} (see Figure \ref{fig:moneyplot}) conclusively demonstrates that the dipole mode suppression arises from a phenomenon within the core.  We have demonstrated that strong magnetic fields in the cores of red giants create a greenhouse effect, trapping mode energy within the core and suppressing mode visibility at the surface. Dipole ($\ell=1$)modes ($\ell=1$) modes  are most sensitive to the core and therefore are affected the most. We predict that $\ell=0$ modes in suppressed oscillators will be unaffected (since they do not propagate within the core), while $\ell=2$ modes will be slightly suppressed, and $\ell=3$ modes should exhibit very little suppression. For perfect wave trapping, purely dipole modes only exist in the envelope, with part of their energy leaking into the core as running magneto-gravity waves. If some wave energy does escape the core, it may leave a signature in the form of mixed magneto-gravity acoustic modes which could be used to constrain the internal magnetic field geometry.  %Hence, mixed modes in the usual sense do not exist in stars with suppressed dipole modes.
