Abstract: We investigate the importance of the slow continuum (from linear, ideal magnetohydrodynamics [MHD]) for hot, evacuated, and strongly magnetic fibrils with nonnegligible radial structure. The radial structure allows for both slow and Alfven resonant absorption of acoustic power (in linear, visco-resistive MHD). When calculating how efficiently the acoustic power is absorbed by such ''hot magnetic fibrils,'' embedded in a uniform compressible medium, as a function of the real driving frequency, it is found that the axisymmetric component of the acoustic excitation is absorbed quite strongly for frequencies within the range of the slow continuum.
