Taroyan, Y. and Erdelyi, R. (2008) Global acoustic resonance in a stratified solar atmosphere. Solar Physics, 251 (1-2). pp. 523-531. ISSN 1573-093X
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.
