Statistics of Solar Filament Mass based on CHASE Sun-as-a-star Spectroscopic Observations
T. Y. Xie, Z. H. Zhao, X. Cheng +5
Filaments are cool and dense plasmas suspended in the hot corona of the Sun and other stars. Accurately estimating their masses is of great significance for understanding subsequen…
Limb Shift of the Fe I 6569 Å line on the Sun
H. C. Yu, M. D. Ding, J. Hong +2
The convective motions of solar granules generate a center-to-limb variation of Doppler velocity in the photospheric lines, known as the limb shift effect. This study presents a co…
Data-constrained magnetohydrodynamic simulation of global solar corona including solar wind effects within 2.5
Yihua Li, Guoyin Chen, Jinhan Guo +6
Total solar eclipses (TSEs) provide a unique opportunity to observe the large-scale solar corona. The solar wind plays an important role in forming the large-scale coronal structur…
The Kinematical Behavior of Solar Eruptive Filaments Affected by the Poloidal Magnetic Field
Ye Qiu, Yang Guo, Mingde Ding +3
Kinematics of solar eruptive filaments is one of the important diagnostic parameters for predicting whether solar eruptions would induce geomagnetic storms. Particularly, some geom…
Observational Study of Recurrent Jets: Evolution of Magnetic Flux, Current, and Helicity
Chang Zhou, Yang Guo, Guoyin Chen +2
We observed three recurrent blowout jets in an active regio with Atmospheric Imaging Assembly (AIA) aboard the Solar Dynamics Observatory (SDO). Using Helioseismic Magnetic Imager…
Astronomical image denoising by self-supervised deep learning and restoration processes
Tie Liu, Yuhui Quan, Yingna Su +9
Image denoising based on deep learning has witnessed significant advancements in recent years. However, existing deep learning methods lack quantitative control of the deviation or…
Developing an Automated Detection, Tracking and Analysis Method for Solar Filaments Observed by CHASE via Machine Learning
Z. Zheng, Q. Hao, Y. Qiu +3
Studies on the dynamics of solar filaments have significant implications for understanding their formation, evolution, and eruption, which are of great importance for space weather…
Data-constrained Magnetohydrodynamic Simulation of an Intermediate Solar Filament Eruption
Yang Guo, Jinhan Guo, Yiwei Ni +5
Solar eruptive activities could occur in weak magnetic field environments and over large spatial scales, especially relevant to eruptions involving intermediate or quiescent solar…
On the intensity ratio variation of the Si IV 1394/1403 Å lines during solar flares
Hao-Cheng Yu, J. Hong, M. D. Ding
Context. The Si IV lines at 1394 Å and 1403 Å form in the solar atmosphere at a temperature of K. They are usually considered optically thin, but their opacity can b…
Evaluation of different recipes for chromospheric radiative losses in solar flares
J. Tian, J. Hong, Y. Li +1
Context. Radiative losses are an indispensable part in the numerical simulation of flares. Detailed calculations could be computationally expensive, especially in the chromosphere.…
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…
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…
