Local Acoustic Diagnostics of the Solar Interior

本项目使用局域波诊断技术来研究地下磁与声波相互作用的表面表现。该项目利用NSO对Pomerantz、Harvey、Duvall和Jefferies的南极观测来开发诊断技术，以探测声波与地下磁结构的相互作用。这些技术使PI第一次详细观察了亚光球的磁结构，显示了穿过太阳赤道连接活跃区域带的淹没通量管。这些技术提供了广泛的天气应用，并可能彻底改变我们对太阳内部MHD和太阳能发电机的理解。这些技术将为利用声全息技术探索太阳内部提供观测基础。结果提供了一个独特的机会来打开太阳内部的地方日震学领域。

This project uses local wave diagnostic techniques to study surface manifestations of subsurface magnetic interactions with acoustic waves. The PI used the NSO South Pole observations of Pomerantz, Harvey, Duvall and Jefferies to develop diagnostic techniques to detect interactions of acoustic waves with subsurface magnetic structure. These techniques are giving the PI the first detailed look at subphotospheric magnetic structure, showing submerged flux tubes that cross the solar equator to connect the active region bands. These techniques offer a broad range of synoptic applications and may revolutionize our understanding of solar interior MHD and the solar dynamo. The techniques will be used to develop an obersvational basis for exploring the solar interior by means of acoustic holography. The results offer a unique opportunity to open the solar interior to the field of local helioseismology.
