Properties of Chromospheric Fibrils Around a Quiescent Filament
Qifan Dong, Xiaoli Yan, Zhike Xue +7
Fibrils are dynamic plasma structures in the solar chromosphere. Studying these structures is critical for understanding solar atmospheric heating and mass transportation. The purp…
High-resolution Observations of a C9.3 White-light Flare and Its Impact on the Solar Photosphere
Zhe Xu, Xiaoli Yan, Zhentong Li +4
We present a detailed analysis of a C9.3 white-light flare using high-resolution observations from the New Vacuum Solar Telescope (NVST). The flare occurred near the eastern solar…
The Observations of Magnetic Reconnection During the Interaction Process of Two Active Region Filaments
Zongyin Wu, Zhike Xue, Xiaoli Yan +11
We investigate the interaction between two filaments (F1 and F2) and their subsequent magnetic reconnection in active region (AR) NOAA 13296 and AR NOAA 13293 on May 9, 2023, utili…
Variation in the intensity ratio at each wavelength point of the Si iv 1394/1403 Ã lines. Spectral diagnostics of a bifurcated eruption
Yi'an Zhou, Xiaoli Yan, Zhike Xue +3
Aims. This study aims to investigate the deviation of the intensity ratio of the \ion{Si}{IV} 1394 Ã and 1403 Ã emission lines from the expected value of 2 in the optically thin re…
The hidden magnetic structures of a solar intermediate filament revealed by the injected flare material
X. L. Yan, Z. K. Xue, J. C. Wang +7
Solar filaments are spectacular objects in the solar atmosphere, consisting of accumulations of cool, dense, and partially ionized plasma suspended in the hot solar corona against…
