Chinese Academy of Sciences A study published in The Astrophysical Journal and mainly by Dr. CAI Qiangwei from Luoyang Normal University and Dr. YE Jing from Yunnan Observatories of the Chinese Academy of Sciences reported the numerical work about the supra-arcade fans (SAFs). The findings implied that the formation and evolution of the SAF is related to the turbulence in the flare current sheet. It is found in many observations that a distributed structure named as supra-arcade fan exists above post-flare loops in solar eruptions. The location of the SAF is spatially consistent with various emission sources. Termination shocks (TSs) that are often regarded as an efficient driver for particle acceleration possibly exist in the SAF.
