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…
Observational Technological Innovations and Future Development of the Lijiang Coronagraph
Xuefei Zhang, Yu Liu, Tengfei Song +5
As a core ground-based coronal observation facility in China's low-latitude high-altitude regions, the Lijiang Coronagraph leverages the natural advantages of Lijiang Astronomical…
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…
Atmospheric turbulence profiling with the Multistar Turbulence Monitor
Weisen Huang, Bin Ma, Tengfei Song +5
Accurate characterization of atmospheric optical turbulence is essential for evaluating astronomical sites and optimizing adaptive optics systems. The Multistar Turbulence Monitor…
The R2Pub Telescopes for Surveying: An Overview and Performance Evaluation of the System
Xuan Song, Xiaofeng Wang, Jin Zhu +29
The R2Pub telescope, built by the Beijing Planetarium, is a 60 cm equatorial binocular telescope located at the Daocheng site of Yunnan Observatories in China, at an altitude of ab…
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…
