First observation of magnetic flux rope inside electron diffusion region

Autor: Chen, Z. Z., Fu, H. S., Wang, Z., Guo, Z. Z., Xu, Y., Liu, C. M.

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
