Resonant absorption and the spectrum of 5-min oscillations of the Sun II. Fine structure of the spectrum of 5-min oscillations

The influence of magnetic field on the spectrum of 5-min solar oscillations has been investigated. The calculations have been made within a model of the two-layer shell. The lower non-magnetized layer is characterized by linear decrease of temperature with height while in the upper layer with homogeneous horizontal magnetic field temperature increase, and reaches a coronal value at the height of about 2500km. It is shown that, accounting for resonant absorption, the spectrum of 5-min oscillations has fine structure, which is most noticeable in high degree modes.
