Verification of the Travel Time Measurement Technique and the Helioseismic Inversion Procedure for Sound Speed Using Artificial Data
Konstantin V. Parchevsky, Junwei Zhao, Thomas Hartlep +1
We performed 3D numerical simulations of the solar surface wave field for the quiet Sun and for three models with different localized sound-speed variations in the interior with: (…
Time--Distance Helioseismology Data Analysis Pipeline for Helioseismic and Magnetic Imager onboard Solar Dynamics Observatory (SDO/HMI) and Its Initial Results
J. Zhao, S. Couvidat, R. S. Bogart +6
The Helioseismic and Magnetic Imager onboard the Solar Dynamics Observatory (SDO/HMI) provides continuous full-disk observations of solar oscillations. We develop a data-analysis p…
Local helioseismology of sunspot regions: comparison of ring-diagram and time-distance results
A. G. Kosovichev, S. Basu, R. Bogart +10
Local helioseismology provides unique information about the subsurface structure and dynamics of sunspots and active regions. However, because of complexity of sunspot regions loca…
Numerical Simulation of Excitation and Propagation of Helioseismic MHD Waves in Magnetostatic Models of Sunspots
K. Parchevsky, A. Kosovichev, E. Khomenko +2
We present comparison of numerical simulations of propagation of MHD waves,excited by subphotospheric perturbations, in two different ("deep" and "shallow") magnetostatic models of…
Theoretical modeling of propagation of magneto-acoustic waves in magnetic regions below sunspots
E. Khomenko, A. Kosovichev, M. Collados +2
We use 2D numerical simulations and eikonal approximation, to study properties of MHD waves traveling below the solar surface through the magnetic structure of sunspots. We conside…
Numerical simulation of excitation and propagation of helioseismic MHD waves: Effects of inclined magnetic field
K. V. Parchevsky, A. G. Kosovichev
Investigation of propagation, conversion, and scattering of MHD waves in the Sun is very important for understanding the mechanisms of observed oscillations and waves in sunspots a…
