1 Fig. 5 3D MHD simulation of multiple plasmoid formation and ejection in the vertical current sheet spawned by an erupting flux rope. 3D MHD simulation of multiple plasmoid formation and ejection in the vertical current sheet spawned by an erupting flux rope. Magnetic field lines, traced from equidistant points on the z axis, show the dynamic current sheet between the lower edge of the erupting and strongly expanding flux rope and the slowly growing arcade of reconnected field lines, which represent the arcade of flare loops. The displayed volume, |x| < 2/7, |y| < 0.25, and 2 < z < 8, is stretched by a factor of 7 in the horizontal direction for clarity of the plasmoids, two of which are traced by dashed lines. The short extent in y direction is chosen because many of the small new flux ropes, seen here as the plasmoids, bend upward or downward out of the plane. Time is given in units of the Alfvén time based on the initial flux rope height (z = 1) and the peak Alfvén velocity in the initial configuration. Tingyu Gou et al.
