MHD simulation for investigating evolutionary path of solar magnetic field that emerges, structures itself, erupts, and produces flare
We performed a long-term magnetohydrodynamic simulation of an emerging twisted flux tube to seamlessly reproduce those dynamic processes involved in the
evolution of a solar magnetic field from emergence below a solar surface to eruption toward an interplanetary space. The simulation showed the three distinct phases: initial phase when the twisted flux tube started to emerge below a solar surface, intermediate phase during which flux rope and sigmoid formed in a solar corona, and final phase at which the flux rope erupted toward the interplanetary space, followed by a flare with plasmoid ejection (eruptive flare).
