We examine a strong, coherent, highly impulsive acoustic transient radiated into the solar interior by the flare SOL20110730T02:04-M9.3. The acoustic spectrum of this transient extends out to 10 mHz. The fine diffraction limit of this high-frequency component of the flare acoustic transient allows us to discriminate different source components in operation during the flare. Acoustic-source power density maps of the 10 mHz component show sources that are compact to within the now 760 km diffraction limit of local helioseismic diagnostics for this frequency. One of the acoustic sources found is bifurcated across a sharp penumbral magnetic boundary, the component in the stronger magnetic field temporally lagging its partner. The facility to discriminate this level of acoustic-source detail could open the door to a long sought after understanding of the mechanics of transient emission from solar flares, still a mystery two decades after its discovery. It also suggests that helioseis...

超脉冲太阳耀斑地震学

我们研究了耀斑SOL20110730T02：04-M9.3辐射到太阳能内部的强烈，连贯，高度脉冲的声音瞬变。此瞬态的声谱扩展到10 mHz。火炬声瞬变的高频分量的精细衍射极限使我们能够区分火炬过程中工作中的不同源分量。10 mHz分量的声源功率密度图显示了在该频率的局部高震诊断的现在760 km衍射极限内紧凑的声源。发现的声源之一在一个尖锐的半影磁场边界上分叉，强磁场中的分量暂时滞后于其伙伴。区分这种水平的声源细节的设施可能会为长期了解太阳耀斑的瞬态发射的机理打开大门，但这仍然是发现后二十年的谜团。这也表明日耳炎...
