Formation of a new X-O pair due to high-beta stream and its action to magnetic field. The figure shows the plasma beta in logarithmic scale (grayscale) and the velocity field (blue arrows). Other symbols are as in Fig. 2. The panels a)−e) correspond to time instants t = 5800, t = 5900, t = 6200, t = 6300, and t = 6400, respectively. The gold rhomboid in the panel d) shows the region where the long and narrow magnetic field structure (produced by plasma flow) changes to the plasmoid.
