Although the structure of sunspots has been studied in considerable detail in and above the photosphere, it has only recently been possible to probe the structure beneath the visible surface of the Sun. Recent work shows that this can be done using the scattering of p-mode acoustic waves by spots. This work will be expanded to include the scattering of p-modes from a variety of active regions, the temporal evolution of the scattering properties of emerging and decaying active regions and the reconstruction of the subsurface morphology.

尽管太阳黑子的结构已经被大量的研究， 在光球和上面的细节，它只是最近才被 可以探测可见表面下的结构， 太阳 最近的工作表明，这可以使用散射 p模式声波的点。 这项工作将扩大到 包括来自各种有源区的p模式的散射， 出现的散射特性的时间演变， 衰减活动区和地下重建 形态学
