Caption
We simulate the seismic propagation of a single wave packet through a stabilized solar atmosphere, including a magnetic fluxtube. The initial wave packet interacts with the flux tube, giving rise to mode conversion. Here we observe downward propagation through the flux tube, triggering a re-emerging wave that carries information about the subsurface structure of the flux tube. The video includes the horizontal and vertical velocity component, for magnetic and quiet simulations, plus the instantaneous difference for different depth scopes.
