耀斑环动力学的数值研究

NUMERICAL STUDY ON THE FLARING LOOP DYNAMICS

数值模拟了太阳耀斑环动力学演化的二维磁重联过程。结果表明，在重联Ｘ 点比较高时，演化过程能再现双带耀斑中的耀斑环活动；而重联Ｘ 点比较低时。

Numerical simulations are performed to study the flaring loop dynamics during magnetic reconnection. Two models are considered with different reconnection point heights. In the model with high reconnection point, the results can reproduce the loop motions in the two ribbon flares, while in the model with low reconnection point, the evolution shows a large similarity to the compact flares. It implies that the two types of solar flares could be unified into the same model, where the height of the reconnection point leads to the bifurcation.
