The inversion problem.
Abstract
The authors discuss some fundamental problems associated with inverting helioseismic data to infer properties of the solar interior, and review various methods used to invert frequencies of normal modes of oscillation. After discussing linear methods, the authors present and compare different asymptotic methods that have been used to infer the internal solar sound speed. They also discuss numerical inversions for solar structure, and address the issue of inverting for more than one function. Methods of inverting for the nonspherically symmetric structure of the Sun are presented.
