从BiSON和GOLF观测看太阳活动周期23上p模功率的变化
Variation in p-mode power over solar cycle 23 as seen from BiSON and GOLF observations
摘要:
我们用一种新的技术分析了BiSON和GOLF/SoHO数据,以研究太阳周期23的p模功率变化。我们发现BiSON在上升阶段的平均速度功率降低了约20%,与以前的研究结果一致。我们还发现,高尔夫,在红翼配置,似乎是在一个不同的高度比理论计算的。
英文摘要:
We analyzed BiSON and GOLF/SoHO data with a new technique, to investigate p-mode power variation over solar cycle 23. We found a decrease in the mean velocity power of about 20% for BiSON during the ascending phase, in agreement with previous findings. We also found that GOLF, during the red-wing configuration, seems to be working at a different height than the theoretically computed one.
