Scientific paper

An asymptotic method for reconstructing the sound speed profile in the solar interior based on observable frequencies of five-minute oscillations is described. A significant improvement in the efficiency of reconstructing the central solar regions is achieved due to the inclusion of self-gravitation effects into asymptotic theory and to an improved inversion algorithm. The radius of the base of the convective zone of the sun is estimated to be 0.70 + or - 0.01 solar radii.
