Reconstruction of ASO-S/HXI Solar Flare Hard X-ray Source Images with Physics-Constrained Deep Network
Zou SiZhong, Liu Hui, Su Yang +4
Solar flare hard X-ray imaging is a key diagnostic of flare energy release and electron acceleration. The ASO-S Hard X-ray Imager (HXI) employs 91 bi-grid sub-collimators, compress…
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…
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…
