论文摘要
磁通量绳（MFRS）在磁重新连接过程中起着至关重要的作用。据信它们主要是通过电子扩散区（EDR）中的撕裂模式不稳定性产生的。但是，EDR内部从未观察到它们。在这里，我们介绍了EDR内部MFR的第一个观察。分叉的非福利MFR，宽度为27.5DE，在n方向上为4.8DE，正在远离X线。在MFR内部，检测到强能量耗散。 MFR可以调节EDR中的电场。我们重建了电子尺度MFR的磁性拓扑。我们的研究促进了对MRF的初始状态及其在磁重新连接期间在电子规模过程中的作用的理解。
Magnrtic flux ropes (MFRs) play a crucial role during magnetic reconnection. They are believed to be primarily generated by tearing mode instabilities in the electron diffusion region (EDR). However, they have never been observed inside the EDR. Here, we present the first observation of an MFR inside an EDR. The bifurcated non-force-free MFR, with a width of 27.5de in the L direction and 4.8de in the N direction, was moving away from the X-line. Inside the MFR, strong energy dissipation was detected. The MFR can modulate the electric field in the EDR. We reconstructed magnetic topology of the electron-scale MFR. Our study promotes understanding of MRFs' initial state and its role in electron-scale processes during magnetic reconnection.
