Statistical Study of Solar Prominence Plumes Based on NVST H Observations
Yangrui Chen, Yijun Hou, Jincheng Wang +9
Plumes are one of the most representative dynamic features observed in prominences and play a key role in mass and magnetic transport within them. However, their physical nature an…
Research on the Flat Field Measurement Method of Coronagraph
Yulong Feng, Xuefei Zhang, Hongfei Liang +4
The solar corona has an extremely low density, and its brightness is only about one millionth of that of the photosphere. High-dynamic-range imaging of its faint structure is there…
Forward Modeling of Dust-Induced Stray Light in Ground-Based Coronagraphs: A Dual-Path Monitoring Approach for High-Precision Inner Corona Observations
Xiande Liu, Xuefei Zhang, Yu Liu +5
High-precision ground-based observations of the inner corona (1.05-2.0 R_sun) are fundamentally constrained by instrumental stray light, particularly the additive background from d…
The First Scientific Flight and Observations of the 50-mm Balloon-Borne White-Light Coronagraph
Kaifeng Kang, Min Huang, Yang Liu +13
A 50-mm balloon-borne white-light coronagraph (BBWLC) to observe whitelight solar corona over the altitude range from 1.08 to 1.50 solar radii has recently been indigenously develo…
Some Questions and Challenges in Measurements of Solar Magnetic Fields
Hongqi Zhang, Jiangtao Su, Xiaofan Wang +4
Huairou Solar Observing Station of the National Astronomical Observatories of the Chinese Academy of Sciences has been in operation since 1987. Successful observations of the solar…
Investigating the Behavior and Spatiotemporal Variations of Green Line Emission in the Solar Corona
Jacob Oloketuyi, Yu Liu, Linhua Deng +6
Understanding coronal structure and dynamics can be facilitated by analyzing green-line emission, which enables the investigation of diverse coronal structures such as coronal loop…
