亮桥与冕环关系的研究进展
Research Progress of the Relationship Between Light Bridges and Coronal Loops
摘要
Abstract
The light bridge is a common structure within sunspots that typically triggers a series of eruptive activities and influences the evolution of sunspots.This article focuses on elucidating the inhibitory relationship between light bridges and coronal loops.By utiliz-ing data from the Solar Dynamics Observatory(SDO),including the Atmospheric Imaging Assembly(AIA)for extreme ultraviolet(EUV)imaging and the Helioseismic and Magnetic Imager(HMI)for line-of-sight and vector magnetograms,we performed a statistical analysis of a large dataset,revealing the prevalent characteristics of the inhibitory features between light bridges and coronal loops.The regions with missing coronal loops are primarily located at the umbra-penumbra boundary near the anchor point of the light bridge.In this region,as the light bridge evolves and changes its morphology,the appearance and disappearance of coronal loops are observed.Analysis of HMI magnetogram data indicates that the light bridge anchoring region is often accompanied by small magnetic fields of opposite polarity.It can be inferred that the magnetic field lines of the light bridge anchor point are connect-ed to the surrounding small magnetic fields of opposite polarity,forming a short-circuited magnetic loop.However,due to the relatively short length of the loop,it does not extend into the corona,thus preventing the observation of coronal loops in the corona.Based on the research findings,a model describing the magnetic connectivity between light bridges and coronal loops is proposed,which can explain many physical processes associated with light bridges.关键词
