Flux-loss of buoyant ropes interacting with convective flows

摘要: We present 3-d numerical magneto-hydrodynamic simulations of a buoyant, twisted magnetic flux rope embedded in stratied, solar-like model convection zone. The is given an initial twist such that it neither kinks nor fragments during its ascent. Moreover, energy content with respect to chosen so the retains basic geometry while being deflected from purely vertical ascent by convective flows. show advected away core as interacts convection. results thus support idea amount toroidal stored at or near bottom solar zone may currently be underestimated.
