摘要
本文针对历史上发生的特大太阳活动事件,探讨其触发因素,采用天体力学方法,计算特定时间太阳系九大行星对日面上耀斑活动区域的摄动力,结果表明:在多数情况下(22个事件中有16个),行星对日面耀斑活动区的摄动力是比较大的。此外,对近几个太阳活动周的部分时段进行摄动力演化的连续计算表明:行星摄动力变化周期与太阳活动的变化周期十分符合,由此进一步证明了太阳活动受行星作用力的调制。太阳耀斑的爆发,活动区的出现。除太阳本身的物理条件外,行星运动对太阳活动的影响也是不可忽视的因素。
In this paper, the relation between solar activity and planetary perturbation is studied to search triggering factors of solar activity. The total perturbing forces by all the major planets have been calculated for the solar activity regions where the large flares occurred. 16 events among the 22 arbitrarily selected large flares occurred within 3 days before or after the local maxima of the perturbing forces. Besides, the secular evolutions of perturbing forces have also been computed. The varieties of perturbative forces display periodicities which coincide closely with that of solar activities. These results show that the disturbing forces of major planets are an important factor affecting solar activities.
