Solar observation with the Fourier transform spectrometer I : Preliminary results of the visible and near-infrared solar spectrum
Xianyong Bai, Zhiyong Zhang, Zhiwei Feng +6
The Fourier transform spectrometer (FTS) is a core instrument for solar observation with high spectral resolution, especially in the infrared. The Infrared System for the Accurate…
Infrared diagnostics of the solar magnetic field with Mg I 12 m lines: forward-model results
Xin Li, YongLiang Song, H. Uitenbroek +3
The Mg I 12.32 and 12.22 m lines are a pair of emission lines that present a great advantage for accurate solar magnetic field measurement. They potentially contribute to the di…
A nonlinear solar magnetic field calibration method for the filter-based magnetograph by the residual network
Jingjing Guo, Xianyong Bai, Yuanyong Deng +5
The method of solar magnetic field calibration for the filter-based magnetograph is normally the linear calibration method under weak-field approximation that cannot generate the s…
Doppler shift oscillations of a sunspot detected by CYRA and IRIS
D. Li, X. Yang, X. Y. Bai +4
Context. The carbon monoxide (CO) molecular line at around 46655 A in solar infrared spectra is often used to investigate the dynamic behavior of the cold heart of the solar atmosp…
Automatic Detection and Correction Algorithms for Magnetic Saturation in the SMFT/HSOS longitudinal Magnetograms
Haiqing Xu, Suo Liu, Jiangtao Su +8

A New Comprehensive Data Set of Solar Filaments of 100 yr Interval. I
GangHua Lin, GaoFei Zhu, Xiao Yang +12
Filaments are very common physical phenomena on the Sun and are often taken as important proxies of solar magnetic activities. The study of filaments has become a hot topic in the…
A Non-Linear Magnetic Field Calibration Method for Filter-Based Magnetographs by Multilayer Perceptron
JingJing Guo, XianYong Bai, YuanYong Deng +5
For filter-based magnetographs, the linear calibration method under the weak-field assumption is usually adopted; this leads to magnetic saturation effect in the regions with stron…
Solar Filament Recognition Based on Deep Learning
GaoFei Zhu, GangHua Lin, DongGuang Wang +2
