Spectral Observations and Modeling of a Solar White-light Flare Observed by CHASE
De-Chao Song, Jun Tian, Y. Li +11
The heating mechanisms of solar white-light flares remain unclear. We present an X1.0 white-light flare on 2022 October 2 (SOL2022-10-02T20:25) observed by the Chinese \ha\ Solar E…
Winking filaments due to cyclic evaporation-condensation
Yuhao Zhou, Xiaohong Li, Jie Hong +1
Observations have shown that some filaments appear and disappear in the H line wing images periodically. There have been no attempts to model these "winking filaments" thus far.…
Statistical analysis of the Si I 6560.58 Å line observed by CHASE
Jie Hong, Ye Qiu, Qi Hao +4
The Si I 6560.58 Å line in the H blue wing is blended with a telluric absorption line from water vapor in ground-based observations. Recent observations with the space-based tel…
Imaging and Spectroscopic Observations of the Dynamic Processes in Limb Solar Flares
Ke Yu, Y. Li, Jie Hong +2
We investigate various dynamic processes including magnetic reconnection, chromospheric evaporation, and coronal rain draining in two limb solar flares through imaging and spectros…
Calibration procedures for the CHASE/HIS science data
Ye Qiu, ShiHao Rao, Chuan Li +17
The Hα line is an important optical line in solar observations containing the information from the photosphere to the chromosphere. To study the mechanisms of solar eruptions and t…
An approximate recipe of chromospheric radiative losses for solar flares
Jie Hong, Mats Carlsson, M. D. Ding
Radiative losses in the chromosphere are very important in the energy balance. There have been efforts to make simple lookup tables for chromospheric radiative losses in the quiet…
Diagnosing the Optically Thick/Thin Features Using the Intensity Ratio of Si IV Resonance Lines in Solar Flares
Yi-an Zhou, Jie Hong, Y. LI +1
In the optically thin regime, the intensity ratio of the two Si IV resonance lines (1394 and 1403 Å ) are theoretically the same as the ratio of their oscillator strengths, which i…
Revisiting the Spectral Features of Ellerman Bombs and UV Bursts. I. Radiative Hydrodynamic Simulations
Jie Hong, Ying Li, M. D. Ding +1
Ellerman bombs (EBs) and UV bursts are both small-scale solar activities that occur in active regions. They are now believed to form at different heights in the lower atmosphere. I…
Simulations of solar filament fine structures and their counterstreaming flows
Y. H. Zhou, P. F. Chen, J. Hong +1
Solar filaments, also called solar prominences when appearing above the solar limb, are cold, dense materials suspended in the hot tenuous solar corona, consisting of numerous long…
The Lyman-alpha Emission in Solar Flares. I. a Statistical Study on Its Relationship with the 1--8 Å Soft X-ray Emission
Zhichen Jing, Wuqi Pan, Yukun Yang +6
We statistically study the relationship between the Lyman-alpha (\lya) and 1--8 Å soft X-ray (SXR) emissions from 658 M- and X-class solar flares observed by the {\em Geostationary…
Spectroscopic Observations of High-speed Downflows in a C1.7 Solar Flare

In this paper, we analyze the high-resolution UV spectra for a C1.7 solar flare (SOL2017-09-09T06:51) observed by the \textit{Interface Region Imaging Spectrograph} (\textit{IRIS})…
Radiative Hydrodynamic Simulations of the Spectral Characteristics of Solar White-light Flares
Yu-Tong Yang, Jie Hong, Ying Li +2
As one of the most violent activities in the solar atmosphere, white-light flares (WLFs) are generally known for their enhanced white-light (or continuum) emission, which primarily…
