Demonstration of how magnetic reconnection expands the flux rope and shifts its center. Top row: Temperature evolution in megakelvin (MK) for σ = 1. Thin black lines trace magnetic arcades, the thick black line marks the separatrix, and the blue line marks a tracked magnetic arcade that eventually reconnects into a closed magnetic field line. The top white cross marks the flux rope center, defined as the only point within the flux rope with a vanishing magnetic curvature. The lower white cross marks the X-point, defined as another isolated point with zero magnetic curvature. Bottom row: Schematic cartoon illustrating the ongoing process from our simulation in a simplified manner.
