The Lyman-alpha Emission in Solar Flares. II. A Statistical Study on Its Relationship with the White-light plus Soft X-ray Emission
De-Chao Song, Ying Li, Qiao Li +1
The hydrogen \lya\ line and the white-light (WL) continuum are two key diagnostics of energy transport in the lower atmosphere during solar flares, yet their relationship remains p…
The M- and X-class White-light Flares in Super Active Region NOAA 13664/13697 Observed by ASO-S/LST/WST
Zhichen Jing, Ying Li, Jingwei Li +1
Solar white-light flares (WLFs) have been observed since 1859, but their occurrence rate is not yet fully understood. The physical properties of WLFs in super active regions (SARs)…
Unveiling Spatiotemporal Properties of the Quasi-periodic Pulsations in the Balmer Continuum at 3600 Ã in an X-class Solar White-light Flare
De-Chao Song, Marie Dominique, Ivan Zimovets +11
Quasi-periodic pulsations (QPPs) in the Balmer continuum of solar white-light flares (WLFs) are rarely reported, and accurately pinpointing the spatial source of flaring QPPs remai…
Improving image quality of the Solar Disk Imager (SDI) of the Lyman-alpha Solar Telescope (LST) onboard the ASO-S mission
Hui Liu, Hui Li, Sizhong Zou +11
The in-flight calibration and performance of the Solar Disk Imager (SDI), which is a pivotal instrument of the Lyman-alpha Solar Telescope (LST) onboard the Advanced Space-based So…
Various Features of the X-class White-light Flares in Super Active Region NOAA 13664
Ying Li, Xiaofeng Liu, Zhichen Jing +8
Super active region NOAA 13664 produced 12 X-class flares (including the largest one, an occulted X8.7 flare, in solar cycle 25 so far) during 2024 May 8-15 and 11 of them are iden…
Asymmetric Hard X-ray Radiation of Two Ribbons in a Thermal-Dominated C-Class Flare
Guanglu Shi, Li Feng, Jun Chen +9
The asymmetry in hard X-ray (HXR) emission at the footpoints (FPs) of flare loops is a ubiquitous feature closely associated with nonthermal electron transport. We analyze the asym…
