The influence of a steady equilibrium state on p- and f- modes is evaluated theoretically for a simple model of the solar plasma, consisting of a polytrope and steady solar interior, above which is an isothermal magnetic atmosphere. Frequency changes and Doppler shifts in phase factors, due to the presence of a steady interior, are calculated analytically in the long-wavelength approximation using hypergeometric functions. The obtained dispersion relation is solved numerically for other cases.
