恒星磁活动的地震信号预测

Forecasting Seismic Signatures of Stellar Magnetic Activity

W. A. Dziembowski

摘要:

对于太阳,各种活动测量和振荡频率之间的紧密相关性是有据可查的。对于其他恒星,我们有大量关于磁场活动及其变化的数据,但还没有关于其地震特征的数据。提出了一种基于太阳关系标度的恒星活动引起的频率变化的预测方法。这种活动的地震特征应该可以在几年内的数据中测量出来。

英文摘要:

For the Sun, a tight correlation between various activity measures and oscillation frequencies is well documented. For other stars, we have abundant data on magnetic activity and its changes but not yet on its seismic signature. A prediction of the activity induced frequency changes in stars based on scaling the solar relations is presented. This seismic signature of the activity should be measurable in the data expected within few years.
