The Alignment of High-resolution Solar Prominence Images Observed by the New Vacuum Solar Telescope
Yunfang Cai, Yongyuan Xiang, Kaifan Ji
High spatial resolution observation of solar prominence is an important observation subject of the New Vacuum Solar Telescope (NVST). While the current level of observation and ima…
Multiwavelength Observations for a Double-decker Filament Channel in AR 13102
Yin Zhang, Baolin Tan, Quan Wang +8
We present the observational evidence of the existence of a double-decker filament channel (FC) by using observations in extreme ultraviolet and Hα wavelengths. For both FCs, the…
Fundamental Parameters for Totally Eclipsing Contact Binaries Observed by TESS
Xu Ding, KaiFan Ji, ZhiMing Song +5
Totally eclipsing contact binaries provide a unique opportunity to accurately determine mass ratios through photometric methods alone, eliminating the need for spectroscopic data.…
Detection of Semidetached Eclipsing Binaries from TESS
Xu Ding, KaiFan Ji, QiYuan Cheng +4
Semidetached binaries, distinguished by their mass transfer phase, play a crucial role in elucidating the physics of mass transfer within interacting binary systems. To identify th…
A method of Extracting Flat Field from Real Time Solar Observation Data
YaHui Jin, Hui Liu, KaiFan Ji +2
Existing methods for obtaining flat field rely on observed data collected under specific observation conditions to determine the flat field. However, the telescope pointing and the…
Simultaneous existence of the ocsillations, counterstreaming flows and mass injections in solar quiescent prominences
X. L. Yan, Z. K. Xue, J. C. Wang +8
Solar prominences are very spectacular structures embedded in the tenuous and hot solar corona. The counterstreaming flows, a common feature in solar quiescent prominences, have be…
