Inversion of Asymptotic Gravity-Mode Frequencies and its Application to the Sun
Solar gravity modes can be used to probe the stratification below the convection zone. An asymptotic formula for high-order gravity-mode frequencies has been obtained in terms of a stratification parameter ß. The domain of validity of this formula is investigated by least-squares regression of frequencies obtained from a theoretical model. Random noise is introduced to simulate real observations. An estimate is made of the critical noise-level above which ß cannot be inferred.
