2005年1月15日太阳耀斑引发的日震分析。II：磁震研究
Helioseismic analysis of the solar flare-induced sunquake of 2005 January 15. II: A magneto-seismic study
摘要：
2005年1月15日，活动区AR 10720产生了一个X1.2的太阳耀斑，引发了光球层的高水平地震活动。本文用日震全息术探测了震源，并作了详细分析。在6兆赫与2兆赫带宽的出口功率图显示了一个紧凑的声源强烈相关的冠状环的脚点，托管耀斑。我们提出了一个磁地震研究这个活跃的区域，以了解，第一次，磁拓扑结构的日冕领域，主机的声学活跃的太阳耀斑。伴随的分析试图回答这样的问题：磁场能作为一个屏障，阻止地震波从太阳地震的焦点传播出去吗？而且，什么是最有效的磁结构，将促进发展的一个强大的震源在光球？
英文摘要：
On 2005 January 15, the active region AR10720 produced an X1.2 solar flare that induced high levels of seismicity into the photospheric layers. The seismic source was detected using helioseismic holography and analysed in detail in Paper I. Egression power maps at 6 mHz with a 2 mHz bandwidth revealed a compact acoustic source strongly correlated with the footpoints of the coronal loop that hosted the flare. We present a magneto-seismic study of this active region in order to understand, for the first time, the magnetic topological structure of a coronal field that hosts an acoustically active solar flare. The accompanying analysis attempts to answer questions such as: Can the magnetic field act as a barrier and prevent seismic waves from spreading away from the focus of the sunquake? And, what is the most efficient magnetic structure that would facilitate the development of a strong seismic source in the photosphere?
