日冕中的高能粒子
High Energy Particles in the Solar Corona
摘要:
集体安培定律相互作用产生穿过太阳黑子进入然后离开日冕的磁通量管,这允许在稳态下的低能核反应和如果磁通量管在诸如太阳耀斑的剧烈事件中爆炸的高能粒子反应。丝状磁通管本身是安培电流的涡流,以龙卷风的方式在大致圆柱形的几何形状中循环。磁场线平行于涡旋的核心,并在很大程度上被限制在涡旋的核心内。因此,涡流可以被看作是围绕磁通量的长载流线圈,并且受到感应法拉第定律和安培定律的影响。这些定律确定了(i)可能定期发生的低能太阳核反应和(ii)当磁通量线圈爆炸成剧烈的偶发事件(如太阳耀斑或日冕物质抛射)时发生的高能电-弱相互作用的能量尺度。
英文摘要:
Collective Ampere law interactions producing magnetic flux tubes piercing through sunspots into and then out of the solar corona allow for low energy nuclear reactions in a steady state and high energy particle reactions if a magnetic flux tube explodes in a violent event such as a solar flare. Filamentous flux tubes themselves are vortices of Ampere currents circulating around in a tornado fashion in a roughly cylindrical geometry. The magnetic field lines are parallel to and largely confined within the core of the vortex. The vortices may thereby be viewed as long current carrying coils surrounding magnetic flux and subject to inductive Faraday and Ampere laws. These laws set the energy scales of (i) low energy solar nuclear reactions which may regularly occur and (ii) high energy electro-weak interactions which occur when magnetic flux coils explode into violent episodic events such as solar flares or coronal mass ejections.
