我们利用GeoTail数据发现了遥远磁尾中具有“心形”结构的等离子体群。我们还发现在心形结构的界面上存在中、慢激波。心形等离子体通道前的血浆片密度明显大于平均血浆片密度。这些结果支持了近地中性线(NENL)产生的等离子体团可能由于等离子体片中磁流体速度的不均匀而演化成心形的观点。
We discovered plasmoids which have the “heart‐shape” structure in the distant magnetotail by using the Geotail data. We also showed the existence of intermediate and slow shocks in the interface of heart shape structure. The plasma sheet density just before the heart‐shaped plasmoid passage appeared to be larger than that of the averaged case. These results support the idea that the plasmoid generated in the near‐Earth neutral line (NENL) may evolve into the heart‐shape due to the nonuniform MHD velocities in the plasma sheet.
