Full waveform inversion

Abstract

Inferring interior properties of the Sun from photospheric measurements of the seismic wavefield constitutes the helioseismic inverse problem. Deviations in seismic measurements (such as wave travel times) from their fiducial values estimated for a given model of the solar interior imply that the model is inaccurate. In this section, we implement iterative inversions to obtain the sub-surface structure of perturbations. The model can be successively improved using either steepest descent or Krylov-subspace techniques such as conjugate gradient, or limited-memory Broyden-Fletcher-Goldfarb-Shanno method.
