| Abstract: |
It is suggested that emerging flux build up magnetic energy in the solar corona that could become the source of flares or jets. Emerging flux also plays an important role in active region formation and disappearance. To investigate these phenomena, it is necessary to study the evolution of an emerging flux from the convection zone to the corona. The solar atmosphere is highly stratified by gravity. For example, the density ratio between photosphere and corona is about ~ 108. However, to study emerging flux process by numerical simulations, it is needed to treat this process with that highly stratified calculation domain. In this paper, we introduce our numerical simulation results for (1) X-ray jets associated with emerging flux and magnetic reconnection in the solar corona, (2) twisted magnetic flux tube emergence into the solar corona, and (3) surge caused by emerging flux tube. |
