Scientific paper

Global adiabatic p-modes are modelled by an asymptotic theory, taking into account the influence of the solar atmosphere on the formation of the eigenoscillations: waves of the whole frequency range 2-10 mHz are now reaching the chromosphere-corona transition region (CCTR) by the tunneling of acoustic waves through the atmospheric barriers. The main acoustic cavity inside the Sun becomes considerably extended in this way, leading to a change of frequencies: low frequencies are increased, while high frequencies are decreased. The transition from low p-mode frequencies to high peak frequencies >6mHz is smooth. The imaginary parts of the frequencies indicate a decay of the amplitudes, resulting from considerable energy losses by tunneling from the main cavity. A penetration of linear p-modes to the corona is impossible. The behavior of the CCTR is that of a free surface: the p-modes may drive forced surface gravity waves of this free surface.
