Measuring the solar meridional flow from perturbations of eigenfunctions of global oscillations

Roth, M.; Schad, A.; Timmer, J.

We present a new concept to infer the meridional flow in the deep solar interior from global oscillation data. This concept is based on the estimation of the coupling strengths of p-mode eigenfunctions mediated by the meridional flow. We illustrate the performance of the method using simulations and present first inversion results of a large-scale…
