Spatial stratification of acoustic oscillations in the solar photosphere
Space-time variations of solar atmosphere parameters are derived by solving non-equilibrium radiation transfer problem. Acoustic oscillations were extracted using k − ω filtration of variations. In the lower photosphere there are evanescent remnants of underphotosphere oscillations; in the middle an...

Space-time variations of solar atmosphere parameters are derived by solving non-equilibrium radiation transfer problem. Acoustic oscillations were extracted using k − ω filtration of variations. In the lower photosphere there are evanescent remnants of underphotosphere oscillations; in the middle and high photosphere there are discrete sources of oscillations, which are excited by granule decay and formation of a new intergranule. The photosphere is penetrated by narrow “channels”, by which energy of fluctuations tunnels with minimal losses into the higher atmosphere layers; such “channels” arise mostly between ascending and descending flows. Particularities of the wave propagation in the solar atmosphere are determined by relationship between wavelength and the effective size of inhomogeneities. |
