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…
Sensitivity of helioseismic travel-times to the imposition of a Lorentz force limiter in computational helioseismology
Hamed Moradi, Paul S. Cally
The rapid exponential increase in the Alfvén wave speed with height above the solar surface presents a serious challenge to physical modelling of the effects of magnetic fields on…
Seismology of the Wounded Sun
Paul S. Cally, Hamed Moradi
Active regions are open wounds in the Sun's surface. Seismic oscillations from the interior pass through them into the atmosphere, changing their nature in the process to fast and…
The Current State-Of-The-Art In Active Region Seismology
Hamed Moradi
Helioseismology is the study of the variations in the internal structure and properties of the dynamics of the Sun from measurements of its surface oscillations. With the 2010 laun…
Constructing and Characterising Solar Structure Models for Computational Helioseismology
Hannah Schunker, Robert Cameron, Laurent Gizon +1
In this paper, we construct background solar models that are stable against convection, by modifying the vertical pressure gradient of Model S (Christensen-Dalsgaard et al., 1996,…
From GHz to mHz: A Multiwavelength Study of the Acoustically Active 14 August 2004 M7.4 Solar Flare
J. C. Martinez-Oliveros, H. Moradi, D. Besliu-Ionescu +3
We carried out an electromagnetic acoustic analysis of the solar flare of 14 August 2004 in active region AR10656 from the radio to the hard X-ray spectrum. The flare was a GOES so…
