Helioseismology provides important tools for studying solar internal structure and dynamics, and for space weather forecast. For testing and correct interpretation of inversion results, as well as advancing our general understanding of wave propagation in stars, numerical simulations of wave propagation promise to be immensly valuable. We present a new numerical method and code for studying the 3D propagation of acoustic and MHD waves in the Sun as a full sphere. The waves are excited randomly, and are propagated through a statitionary solar model which includes localized structures such as models of sunspots.
Here, we show results from simulations for structures with localized variations of the sound speed compared with the averaged, quiet Sun. For instance, we show how the oscillation power varies from the quiet Sun model, and compare with observations. The simulation results also provide artificial data for testing time-distance helioseismology inferences including far-side imaging and probing the tachocline structure.
This research was supported by an appointment to the NASA Postdoctoral Program at Ames Research Center, administered by Oak Ridge Associated Universities through a contract with NASA.
