太阳黑子本影点的理论解释

本文假设在太阳黑子磁管内出现局部横向扰动磁场,然后利用中性片理论较为满意地解释了黑子本影点的形成.并利用Petschek的理论公式估算了本影点的温度、磁场和寿命,所得结果与观测值符合较好. 

The Explanation of Umbral Dot of Sunspot

In this paper, the form of umbral dots of sunspot was satisfactorily explained by a mechanism of local perturbations in a magnetic tube of sunspot along with the theory of Petschek’s neutral sheet. On the other hand, the special properties of umbral dots of sunspot such as the temperature, magnetic field and its life-time were estimated by Petschek’s formulae. The obtained results were agreed fairly well with observations.
