Crynodeb
The upward propagation of linear acoustic waves in a gravitationally
stratified solar atmosphere is studied. The wave motion is governed by
the Klein Gordon equation, which contains a cutoff frequency
introduced by stratification. The acoustic cutoff may act as a potential
barrier when the temperature decreases with height. It is shown that
waves trapped below the barrier could be subject to a resonance that
extends into the entire unbounded atmosphere of the Sun. The parameter
space characterizing the resonance is explored.
