1700年以来的太阳磁场:I.太阳黑子群出现的特征及蝴蝶图的重建

The solar magnetic field since 1700: I. Characteristics of sunspot group emergence and reconstruction of the butterfly diagram

Jie Jiang, Robert H. Cameron, Dieter Schmitt, Manfred Schuessler

摘要:

我们使用的太阳黑子群的历史记录,由英国皇家格林尼治天文台编制的太阳黑子数一起导出太阳黑子群出现的周期相位和强度的依赖性的统计特性。特别是,我们讨论了太阳黑子群的纬度,经度,面积和倾斜角的函数的周期强度和时间在太阳活动周期。利用这些经验特征,根据Wolf和群黑子数重建了1700年以后的太阳黑子群出现时纬图(蝴蝶图)。这种重建将有助于研究太阳磁场的长期演化。

英文摘要:

We use the historic record of sunspot groups compiled by the Royal Greenwich Observatory together with the sunspot number to derive the statistical properties of sunspot group emergence in dependence of cycle phase and strength. In particular we discuss the latitude, longitude, area and tilt angle of sunspot groups as functions of the cycle strength and of time during the solar cycle. Using these empirical characteristics the time-latitude diagram of sunspot group emergence (butterfly diagram) is reconstructed from 1700 onward on the basis of the Wolf and group sunspot numbers. This reconstruction will be useful in studies of the long-term evolution of the Sun's magnetic field.
