Acoustic wave propagation in the solar atmosphere. V. Observations versus simulations
J. Theurer, P. Ulmschneider, W. Kalkofen
We study the evolution of spectra of acoustic waves that are generated in the convection zone and propagate upward into the photosphere, where we compare the simulated acoustic spe…

Acoustic wave propagation in the solar atmosphere. IV Nonadiabatic wave excitation with frequency spectra
J. Theurer, P. Ulmschneider, M. Cuntz
We study the response of the solar atmosphere to excitations by large amplitude acoustic waves with radiation damping now included. Monochromatic adiabatic waves, due to unbalanced…
