Towards Waveform Heliotomography: Observing Interactions of Helioseismic Waves with a Sunspot
Junwei Zhao, Alexander G. Kosovichev, Stathis Ilonidis
We investigate how helioseismic waves that originate from effective point sources interact with a sunspot. These waves are reconstructed from observed stochastic wavefields on the…

Determining Absorption, Emissivity Reduction, and Local Suppression Coefficients inside Sunspots
Stathis Ilonidis, Junwei Zhao
The power of solar acoustic waves is reduced inside sunspots mainly due to absorption, emissivity reduction, and local suppression. The coefficients of these power-reduction mechan…
