活动区新浮磁流和暗条的激活

用数值计算方法探讨了新浮磁流驱动下暗条运动的基本规律,计算表明,活动区新肖磁流是驱动暗条运动导致暗条激少在的有效机制之一,这个过程是通过暗条电流和背景磁场的相互作用来实现的,当选取不同强度的浮现磁流时,暗条可出现周期性振荡,激活上升和闪烁,此外,对同性极磁流浮现,当浮现强度足够强时,暗条一开始就会下沉。

EMERGENT MAGNETIC FLUX AND FILAMENT ACTIVATION IN ACTIVE REGIONS

In this paper,the basic regularity of filament motion driven by emerging magnetic flux is first explored numerically.The results show that the emerging flux in the active region is an effective mechanism for driving filament motion and causing ilament activation.This process can be realized by the interaction between the filament current and background magnetic field in the active region. With different emerging flux intensities,the periodic oscillation,activation rising and "twinkle" can occur in the filament.Moreover,if the polarity of emerging flux is the same with that of the filament,the filament would drop down at the beginning of its evolution when the emerging flux is strong enough.
