Validation of Time-Distance Helioseismology by Use of Realistic Simulations of Solar Convection
Junwei Zhao, Dali Georgobiani, Alexander G. Kosovichev +3
Recent progress in realistic simulations of solar convection have given us an unprecedented opportunity to evaluate the robustness of solar interior structures and dynamics obtaine…
Three dimensional numerical simulations of acoustic wave field in the upper convection zone of the Sun
K. V. Parchevsky, A. G. Kosovichev
Results of numerical 3D simulations of propagation of acoustic waves inside the Sun are presented. A linear 3D code which utilizes realistic OPAL equation of state was developed by…
Local helioseismology and correlation tracking analysis of surface structures in realistic simulations of solar convection
Dali Georgobiani, Junwei Zhao, Alexander Kosovichev +3
We apply time-distance helioseismology, local correlation tracking and Fourier spatial-temporal filtering methods to realistic supergranule scale simulations of solar convection an…
Surface Magnetism Effects in Time-Distance Helioseismology
Junwei Zhao, Alexander G. Kosovichev
Recent observations of helioseismic holography revealed that magnetic fields inclined to the line-of-sight direction could cause systematic variations in measured acoustic phase sh…
