\label{Fig:cartoon} In normal red giant stars acoustic waves excited in the envelope can couple to gravity waves in the radiative core. In the presence of a strong magnetic field in the stellar core, p-modes couple to magneto-gravity and pure Alfven waves instead. Regardless of the details of this process, the energy leaking from the envelope through the evanescent region is scattered into a large number of modes with high harmonic degree $\ell$. High $\ell$ High-$\ell$  modes can not escape the core due to their large evanescent region and are trapped (magnetic greenhouse effect).
