Accurate numerical solutions to the forward problem of local helioseismology

Author: Chris Hanson
We compute acoustic Green’s functions in an axisymmetric solar background model, which may include a meridional flow and differential rotation. The wave equation is solved in the frequency domain using a finite element solver. ... more

Computational Local Helioseismology in the Frequency Domain

Author: Chris Hanson
Forward problems in local helioseismology have thus far been addressed in a semi-analytical fashion using the Born approximation and normal-mode expansions or direct simulations. However, it has proven difficult to take into acco ... more
