Description

Magnetic field dominates wave behaviour in sunspots. The direction of the magnetic field has profound effects on mode conversion, "travel times" (as inferred from local helioseismology), and on wave polarization. These in turn affect what we see when observing spots from different orientations. I will discuss recent work at Monash on both travel time dependence on field direction, and on synthesising observables from wave simulations.
