時間/地點: 2016-03-04 14:00 [S4-1013]

摘要:

* Using measured helioseimic waves on solar surface to probe subsurface structure of sunspots is one of the goals in helioseismology. * The wave-sunspot interaction can be considered as a scattering problem. * This work measures the process of an organized incident wave-packet traveling through a sunspot. From the measured scattered waves, the scattering matrix is computed. * The scattered wave and scattering matrix can be used to infer properties of sunspot in future study.
