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…
Multiwavelength spectroscopic observations of a quiescent prominence
Jianchao Xue, Ping Zhang, Jean-Claude Vial +5
In this paper we focus on the analysis of the multiwavelength spectroscopic observations of a quiescent prominence. The spectral and geometrical parameters in the prominence were d…
Understanding the Lyα Emission Observed by the Solar Disk Imager Aboard the Advanced Space-based Solar Observatory
Yiliang Li, Ping Zhang, Zhengyuan Tian +12
The H I Lyman-alpha (Ly) emission, with a wavelength of 1216 Å, is the brightest solar ultraviolet (UV) line. However, comprehensive observations of the Ly emission line acro…
Patterns of X-ray and -ray Flares: from Blazar to Maganetar and Sun
Haiyun Zhang, Dahai Yan, Lijuan Dong +6
Using Gaussian process methods, we analyzed the light curves of three extreme solar X-ray flares observed by the RHESSI satellite. Their variability characteristics were then compa…
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…
Association between a Failed Prominence Eruption and the Drainage of Mass from Another Prominence
Jianchao Xue, Li Feng, Hui Li +31
Sympathetic eruptions of solar prominences have been studied for decades, however, it is usually difficult to identify their causal links. Here we present two failed prominence eru…
Spectral and Imaging Observations of a C2.3 White-Light Flare from the Advanced Space-Based Solar Observatory (ASO-S) and the Chinese H Solar Explorer (CHASE)
Qiao Li, Ying Li, Yang Su +27
Solar white-light flares are characterized by an enhancement in the optical continuum, which are usually large flares (say X- and M-class flares). Here we report a small C2.3 white…
