Research Fields

Achievements

For 35 cm Solar Magnetic Field Telescope operating at Huairou Solar Observing Station (HSOS), we for the first time obtained the qualitative relationship between Faraday rotation and magnetic field strength;

 

For Solar Magnetism and Optics Monitoring System at HSOS, we qualitatively studied the crosstalk of Stokes I and V to Q and U and developed two methods to remove the effect of solar rotation on measurements of full-disk magnetic fields.

 

With 1.6 m New Solar Telescope operated at Big Bear Solar Observatory, we found fine structures of umbral wavefront trajectories organized in a manner much analogous to galaxy spiral-arm structures. Interestingly, one of them has 3 spiral arms first showing anti-clockwise rotations, then clockwise rotations.
