HXI-DLA2: A Physics-Constrained Deep Learning Algorithm for the ASO-S Hard X-ray Imager
Zou SiZhong, Liu Hui, Su Yang +5
Solar flare hard X-ray imaging is a key diagnostic of flare energy release and electron acceleration. The Hard X-ray Imager (HXI) aboard ASO-S compresses the two-dimensional source…
Twisted-pair unilateral reconnection: A unifying driver for magnetically powered astrophysical bursts
Shu-Ping Yan, Wenhui Yu, Jing Ye +11
Magnetic reconnection in twisted loops has long been invoked as an engine powering energetic transients from black hole accretion to neutron star mergers, yet never directly observ…
Intense Hard X-ray Emissions in C-class Flares: A Statistical Study with ASO-S/HXI Data
Changxue Chen, Yang Su, Wei Chen +3
In the standard model of solar eruptive events, coronal mass ejections (CMEs) and flares are associated with each other through magnetic reconnection initiated by erupting flux rop…
Numerous Bidirectionally Propagating Plasma Blobs near the Reconnection Site of a Solar Eruption
Zhenyong Hou, Hui Tian, Maria S. Madjarska +7
Current sheet is a common structure involved in solar eruptions. However, it is observed in minority of the events and the physical properties of its fine structures during a solar…
A Statistical Investigation of the Neupert Effect in Solar Flares Observed with ASO-S/HXI
Dong Li, Hanyang Dong, Wei Chen +3
The Neupert effect refers to the strong correlation between the soft X-ray (SXR) light curve and the time-integrated hard X-rays (HXR) or microwave flux, which is frequently observ…
A Statistical Study of Solar White-Light Flares Observed by the White-light Solar Telescope of the Lyman-alpha Solar Telescope on the Advanced Space-based Solar Observatory (ASO-S/LST/WST) at 360 nm
Zhichen Jing, Ying Li, Li Feng +26
Solar white-light flares (WLFs) are those accompanied by brightenings in the optical continuum or integrated light. The White-light Solar Telescope (WST), as an instrument of the L…
Observational signature of continuously operating drivers of decayless kink oscillation
Dong Li, Zhentong Li, Fanpeng Shi +7
Decayless kink oscillations, which are nearly omnipresent in the solar corona, are believed to be driven by continuously operating energy supply. In this letter, we investigate an…
