Multiple scattering of waves by a pair of gravitationally stratified flux tubes
Shravan M. Hanasoge, Paul S. Cally
We study the near-field coupling of a pair of flux tubes embedded in a gravitationally stratified environment. The mutual induction of the near-field {\it jackets} of the two flux…
Sub-Wavelength Resolution Imaging of the Solar Deep Interior
Shravan M. Hanasoge, Thomas L. Duvall
We derive expectations for signatures in the measured travel times of waves that interact with thermal anomalies and jets. A series of numerical experiments that involve the dynami…
Numerical Models of Travel-Time Inhomogeneities in Sunspots
H. Moradi, S. M. Hanasoge, P. S. Cally
We investigate the direct contribution of strong, sunspot-like magnetic fields to helioseismic wave travel-time shifts via two numerical forward models, a 3D ideal MHD solver and M…
Scattering of acoustic waves by a magnetic cylinder
L. Gizon, L., S. M. Hanasoge +1
With the aim of studying magnetic effects in time-distance helioseismology, we use the first-order Born approximation to compute the scattering of acoustic plane waves by a magneti…
Seismic Halos Around Active Regions: An MHD Theory
Shravan M. Hanasoge
Comprehending the manner in which magnetic fields affect propagating waves is a first step toward constructing accurate helioseismic models of active region sub-surface structure a…
Global effects of local sound-speed perturbations in the Sun: A theoretical study
S. M. Hanasoge, T. P. Larson
We study the effect of localized sound-speed perturbations on global mode frequencies by applying techniques of global helioseismology on numerical simulations of the solar acousti…
