| Abstract: | We consider the influence of a finite conductivity on the spectrum of solar p-modes (by taking into account their absorption at cusp resonance levels) in a plane two-layer model that consists of an upper isothermal layer with a uniform horizontal magnetic field and a lower adiabatic layer with a linear increase in temperature with depth. We show that an allowance for the finite, but high conductivity of the medium is required only to calculate the eigenfrequencies of the p-modes for which the resonance levels are located almost at the interface between the layers. |
