Inversion of CHASE H Spectral Line during Solar Flares Based on RADYN Dataset via Deep Learning
W. Xu, Q. Hao, Z. Zheng +6
Solar flares represent one of the most intense forms of solar activity. Understanding the evolution of physical parameters in the solar atmosphere during flares is key to studying…
Two-stage primary acceleration in filament initial eruption under a fan-spine magnetic configuration
Haitang Li, Ke Yu, Chang Zhou +6
Understaning the filament rising process is crucial for unveiling the triggering mechanisms of the coronal mass ejections and forecasting the space weather. In this paper, we prese…
Two-Stage Nature of a Solar Flare with Parallel and Semi-Circular Ribbons
Ruifei Huang, Hao Ning, Ze Zhong +6
Flare ribbons with parallel and circular morphologies are typically associated with different magnetic reconnection models, and the simultaneous observation of both types in a sing…
Sun-as-a-star Analysis of the Solar Eruption Source Region Using Ha Spectroscopic Observations of CHASE
Xiaofeng Liu, Yijun Hou, Ying Li +6
Sun-as-a-star analyses serve as a bridge for comparative studies on solar and stellar activities. To investigate the typical Sun-as-a-star Ha temporal spectral characteristics in s…
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…
