Magnetic Activity of F-, G-, and K-type Stars in the LAMOST-Kepler Field
Jinghua Zhang, Shaolan Bi, Yaguang Li +10
Monitoring chromospheric and photospheric indexes of magnetic activity can provide valuable information, especially the interaction between different parts of the atmosphere and th…
Flare Activity and Magnetic Feature Analysis of the Flare Stars
Hadis Goodarzi, Ahmad Mehrabi, Habib khosroshahi +1
We analyze the light curve of 1740 flare stars to study the relationship between the magnetic feature characteristics and the identified flare activity. Coverage and stability of m…
Chirality and magnetic configuration associated with two-ribbon solar flares: AR 10930 versus AR 11158
Han He, Huaning Wang, Yihua Yan +2
The structural property of the magnetic field in flare-bearing solar active regions (ARs) is one of the key aspects for understanding and forecasting solar flares. In this paper, w…
Activity Analyses for Solar-type Stars Observed with Kepler. II. Magnetic Feature Versus Flare Activity
Han He, Huaning Wang, Mei Zhang +3
The light curves of solar-type stars present both periodic fluctuation and flare spikes. The gradual periodic fluctuation is interpreted as the rotational modulation of magnetic fe…
Forced field extrapolation of the magnetic structure of the Halpha fibrils in solar chromosphere
Xiaoshuai Zhu, Huaning Wang, Zhanle Du +1
We present a careful assess of the forced field extrapolation using Solar Dynamics Observatory/Helioseismic and Magnetic Imager (SDO/HMI) magnetogram. The convergence property is c…
Variations of the 3-D coronal magnetic field associated with the X3.4-class solar flare event of AR 10930
Han He, Huaning Wang, Yihua Yan +2
The variations of the 3-D coronal magnetic fields associated with the X3.4-class flare of active region 10930 are studied in this paper. The coronal magnetic field data are reconst…
Activity Analyses for Solar-Type Stars Observed With Kepler. I. Proxies of Magnetic Activity
Han He, Huaning Wang, Duo Yun
Light curves of solar-type stars often show gradual fluctuations due to rotational modulation by magnetic features (starspots and faculae) on stellar surfaces. Two quantitative mea…
Nonlinear force-free coronal magnetic field extrapolation scheme based on the direct boundary integral formulation
Han He, Huaning Wang
