3D simulations of realistic power halos in magneto-hydrostatic sunspot atmospheres: linking theory and observation
Carlos Rijs, S. P. Rajaguru, Damien Przybylski +3
The well-observed acoustic halo is an enhancement in time-averaged Doppler velocity and intensity power with respect to quiet-sun values which is prominent for weak and highly incl…
Directional Time-Distance Probing of Model Sunspot Atmospheres
H. Moradi, P. S. Cally, D. Przybylski +1
A crucial feature not widely accounted for in local helioseismology is that surface magnetic regions actually open a window from the interior into the solar atmosphere, and that th…
MHD wave refraction and the acoustic halo effect around solar active regions - a 3D study
Carlos Rijs, Hamed Moradi, Damien Przybylski +1
An enhancement in high-frequency acoustic power is commonly observed in the solar photosphere and chromosphere surrounding magnetic active regions. We perform 3D linear forward wav…
