The coronal mass ejection productivity of solar active region 13664/8
Lijuan Liu, Yuming Wang, Quanhao Zhang +2
In May 2024, NOAA active region (AR) complex 13664/8 was one of the most productive regions of the current solar cycle, producing 12 X-class flares and over 20 coronal mass ejectio…
Photospheric horizontal magnetic field decrease preceding a major solar eruption
Lijuan Liu, Hanzhao Yang
Significant photospheric magnetic field changes during major solar eruptions -- interpreted as coronal feedback from eruptions to the photosphere -- are well-observed. However, ana…
Why could a new-born active region produce coronal mass ejections?
Hanzhao Yang, Lijuan Liu
Solar active regions (ARs) are the main sources of flares and coronal mass ejections (CMEs). NOAA AR 12089, which emerged on 2014 June 10, produced two C-class flares accompanied b…
The evolution of a spot-spot type solar active region which produced a major solar eruption
Lijuan Liu
Solar active regions (ARs) are the main sources of large solar flares and coronal mass ejections. It is found that the ARs producing large eruptions usually show compact, highly-sh…
On the nature of photospheric horizontal magnetic field increase in major solar flares
Lijuan Liu, Zhenjun Zhou, Yuming Wang +2
Rapid increase of horizontal magnetic field () around the flaring polarity inversion line is the most prominent photospheric field change during flares. It is considered to be…
The Rotation of Magnetic Flux Rope Formed during Solar Eruption
Zhenjun Zhou, Chaowei Jiang, Rui Liu +3
The eruptions of solar filaments often show rotational motion about their rising direction, but it remains elusive what mechanism governs such rotation and how the rotation is rela…
Resolving Two Distinct Thermal X-ray Components in A compound Solar Flare
Zhenjun Zhou, Rui Liu, Jianqing Sun +6
X-ray emission provides the most direct diagnostics of the energy-release process in solar flares. Occasionally, a superhot X-ray source is found to be above hot flare loops of ~10…
The configuration and failed eruption of a complex magnetic flux rope above a δ sunspot region
Lijuan Liu, Jiajia Liu, Jun Chen +4
Aims. We investigate the configuration of a complex flux rope above a δ sunspot region in NOAA AR 11515, and its eruptive expansion during a confined M5.3-class flare. Methods. We…
The Source Locations of Major Flares and CMEs in the Emerging Active Regions
Lijuan Liu, Yuming Wang, Zhenjun Zhou +1
Major flares and coronal mass ejections (CMEs) tend to originate from the compact polarity inversion lines (PILs) in the solar active regions (ARs). Recently, a scenario named as "…
Magnetic Flux of Active Regions Determining the Eruptive Character of Large Solar Flares
Ting Li, Yijun Hou, Shuhong Yang +3
We establish the largest eruptive/confined flare database to date and analyze 322 flares of \emph{GOES} class M1.0 and larger that occurred during 20102019, i.e., almost spannin…
Cause and Kinematics of a Jet-Like CME
Reetika Joshi, Yuming Wang, Ramesh Chandra +3
In this article, we present the multi-viewpoint and multi-wavelength analysis of an atypical solar jet based on the data from Solar Dynamics Observatory, SOlar, and Heliospheric Ob…
Electric Currents through J-shaped and Non-J-shaped Flare Ribbons
Yuwei He, Rui Liu, Lijuan Liu +3
Recently solar flares exhibiting a double J-shaped ribbons in the lower solar atmosphere have been paid increasing attention in the context of extending the two-dimensional standar…
The Relationship between Chirality, Sense of Rotation, and Hemispheric Preference of Solar Eruptive Filaments
Zhenjun Zhou, Rui Liu, Xing Cheng +4
The orientation, chirality, and dynamics of solar eruptive filaments is a key to understanding the magnetic field of coronal mass ejections (CMEs) and therefore to predicting the g…
Formation of a Magnetic Flux Rope in the Early Emergence Phase of NOAA Active Region 12673
Lijuan Liu, Xin Cheng, Yuming Wang +1
In this work, we investigate the formation of a magnetic flux rope (MFR) above the central polarity inversion line (PIL) of NOAA Active Region 12673 during its early emergence phas…
Two Types of Solar Confined Flares
Ting Li, Lijuan Liu, Yijun Hou +1
With the aim of understanding the physical mechanisms of confined flares, we selected 18 confined flares during 2011-2017, and classified the confined flares into two types based o…
Extreme-ultraviolet Late Phase Caused by Magnetic Reconnection over Quadrupolar Magnetic Configuration in a Solar Flare
Zhenjun Zhou, Xin Cheng, Lijuan Liu +3
A second emission enhancement in warm coronal extreme-ultraviolet (EUV) lines (about 2-7 MK) during some solar flares is known as the EUV late phase. Imaging observations confirm t…
Why torus-unstable solar filaments experience failed eruption?
Zhenjun Zhou, Xin Cheng, Jie Zhang +5
To investigate the factors that control the success and/or failure of solar eruptions, we study the magnetic field and 3-Dimensional (3D) configuration of 16 filament eruptions dur…
Rapid buildup of a magnetic flux rope during a confined X2.2 class flare in NOAA AR 12673
Lijuan Liu, Xin Cheng, Yuming Wang +3
Magnetic flux ropes (MFRs) are believed to be the core structure in solar eruptions, nevertheless, their formation remains intensely debated. Here we report a rapid buildup process…
