在过去的几十年里,对恒星磁活动的研究一直是通过光谱和偏振光谱调查来进行的。这不仅可以探测到其他恒星的磁周期,还可以探测到变磁活动。对太阳来说,磁场活动被描述为对流、自转和磁场之间的相互作用。为了研究类太阳恒星的磁活动,我们需要了解表面旋转周期、磁活动的性质和恒星的结构。我们提出了从类开普勒目标的旋转周期、磁活动代理和检测到的磁活动周期方面的研究结果。然后,我们可以将这些信息与星震研究结合起来,对恒星磁活动有一个更广泛的了解。
For the last few decades the investigation of stellar magnetic activity has been conducted through spectroscopic and spectropolarimetric surveys. This led not only to the detection of magnetic cycles in other stars but also to variable and magnetic activity. For the Sun, the magnetic activity is described as the interaction between convection, rotation, and magnetic field. To study magnetic activity of solar-like stars we need to have the knowledge of the surface rotation period, the properties of magnetic activity, and the structure of the stars. We present the results obtained from the studies ofKeplersolarlike targets in terms of rotation periods, magnetic activity proxies and magnetic activity cycles detected. We can then combine this information with asteroseismic studies to have a broader picture of stellar magnetic activity.
