由快MHD波折射产生的太阳黑子地震晕
Sunspot seismic halos generated by fast MHD wave refraction
摘要：
我们提出了一个解释的高频功率过剩周围的活跃地区被称为地震晕。这个想法是基于磁声波在太阳黑子中传播的数值模拟。我们认为，这种过剩可以引起的附加能量注入的快模式波折射在高层大气中由于阿尔芬速度的快速增加。我们的模型定性地解释了晕的大小，并允许对其行为进行一些预测，这些预测可以在未来的观测中进行检查。
英文摘要：
We suggest an explanation for the high-frequency power excess surrounding active regions known as seismic halos. The idea is based on numerical simulations of magneto-acoustic waves propagation in sunspots. We propose that such an excess can be caused by the additional energy injected by fast mode waves refracted in the higher atmosphere due to the rapid increase of the Alfven speed. Our model qualitatively explains the magnitude of the halo and allows to make some predictions of its behavior that can be checked in future observations.
