太阳出射通量区自由磁能的标度律
Scaling laws of free magnetic energy stored in a solar emerging flux region
摘要：
这封信报告了储存在太阳新兴通量区域的自由磁能的标度律，这是理解太阳活动现象（如太阳耀斑和日冕物质抛射）能量学的关键。通过三维磁流体动力学模拟再现了几个不同磁位形的出射磁通区域，得到了这些出射磁通区域中出射磁通量、自由磁能和相对磁螺旋度之间的幂律关系。由于磁通量是一个可观测的量，磁通量和自由磁能之间的标度律可以提供一种方法来估计负责太阳活动现象的不可见的自由磁能。
英文摘要：
This Letter reports scaling laws of free magnetic energy stored in a solar emerging flux region which is a key to understanding the energetics of solar active phenomena such as solar flares and coronal mass ejections. By performing 3-dimensional magnetohydrodynamic simulations that reproduce several emerging flux regions of different magnetic configurations, we derive power law relationships among emerged magnetic flux, free magnetic energy and relative magnetic helicity in these emerging flux regions. Since magnetic flux is an observable quantity, the scaling law between magnetic flux and free magnetic energy may give a way to estimate invisible free magnetic energy responsible for solar active phenomena.
