论文摘要
太阳循环23和24的Helioseisic数据明确表明太阳能动力学随太阳能活动而变化。太阳结构的变化更难以检测。 Basu&Mandel(2004)声称,当时可用的数据揭示了太阳的HEII离子化区的变化。但是,变化的量表明需要比预期的磁场更大的变化。现在,可以使用跨越两个太阳周期的热溶数据,我们使用改进的拟合技术重做了分析。我们发现,与活动相关的HEII离子化区周围区域确实存在变化。由于数据集现在涵盖了两个太阳周期,因此很容易辨别时间变化。
Helioseismic data for solar cycles 23 and 24 have shown unequivocally that solar dynamics changes with solar activity. Changes in solar structure have been more difficult to detect. Basu & Mandel (2004) had claimed that the then available data revealed changes in the HeII ionization zone of the Sun. The amount of change, however, indicated the need for larger than expected changes in the magnetic fields. Now that helioseismic data spanning two solar cycles are available, we have redone the analysis using improved fitting techniques. We find that there is indeed a change in the region around the HeII ionization zone that is correlated with activity. Since the data sets now cover two solar cycles, the time variation is easily discernible.
