PROPAGATION OF ALFVÉN WAVES IN MULTI-LAYER SOLAR ATMOSPHERE MODEL

In this paper, the actual solar atmoshpere is idealized as a multi-isothermal-layer system so as to obtain the energy transmittance of the linear Alfven wave that propagates through such a system in presence of a uniform oblique magnetic field. The result indicates that two-layer models are essentially different to three-layer models. In two-layer models, the temperature jump act as a high pass-filter, while in three-layer models, resonant transfer will take place, the transmittance shows a. vibration. The result reveals that the lower parts of the solar atmopshere are more suitable for those Alfven waves with period of a few seconds to transfer their energy.
