AI 中文摘要
准周期快模磁声波常在太阳耀斑事件中被检测到，但因观测信噪比限制以及耀斑磁拓扑和能量释放强度差异，并非每次耀斑都能观测到。这些结构沿磁构型传播，为日冕磁环境和耀斑区域提供有效诊断。快模准周期振荡波列中的周期性特征携带有关激发过程和传播条件的物理信息，支持对耀斑核心和磁通道特性的定量研究。本文聚焦于2011年8月3日发生在活动区NOAA 11261的一次有详细记录的事件，该事件由GOES M6.0级太阳耀斑同时激发了两个方向相反的准周期振荡波。这些准周期振荡波可分为宽波列和窄波列，窄波列沿漏斗状环传播，宽波列穿过低日冕。观测结果表明，单个耀斑爆发可同时触发宽波和窄波准周期振荡现象。本研究还表明，这种多路径准周期振荡波事件可用于诊断磁场和耀斑核心，展示了多路径准周期振荡波对日冕磁场和耀斑核心的可靠诊断能力。
英文摘要
Quasi-periodic fast-mode magnetoacoustic waves are often detected during solar flare events, although they are not observed in every flare, due to observational signal-to-noise limits and differences in flare magnetic topology and energy release strength. These structures propagate along magnetic configurations and supply effective diagnostics for coronal magnetic environments and flaring regions. Periodic signatures seen in fast-mode QFP wave trains carry physical information about excitation processes and propagation conditions. These signatures support quantitative studies of flare cores and magnetic channel properties. This work focuses on a well-documented event involving two oppositely oriented QFP waves simultaneously excited by a GOES-class M6.0 solar flare that occurred in active region NOAA 11261 on August 3, 2011. These QFP waves can be categorized into broad and narrow wave trains, with the narrow one propagating along funnel-like loops and the broad one moving through the low corona. Observational results suggest that both broad-wave and narrow-wave QFP phenomena can be simultaneously triggered by a single flare eruption. This study also indicates that such multi-path QFP wave events can be utilized to diagnose the magnetic field and the flare's core, and demonstrates the capability of multi-path QFP waves for robust coronal magnetic field and flare core diagnostics.
