P-Modes Scattering by Sunspots

虽然太阳黑子的结构已经在光球层内部和上面进行了相当详细的研究，但直到最近才有可能探测到太阳可见表面之下的结构。最近的研究表明，这可以通过点对p型声波的散射来实现。这项工作将扩展到包括各种活跃区域的p模式散射，新兴和衰减活跃区域散射特性的时间演变以及地下形态的重建。

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.
