We examine the East-West asymmetry of the peak intensity in energetic storm particle (ESP) events using the improved Particle Acceleration and Transport in the Heliosphere (iPATH)…
First report of a solar energetic particle event observed by China's Tianwen-1 mission in transit to Mars
Shuai Fu, Zheyi Ding, Yongjie Zhang +15
Solar energetic particles (SEPs) associated with flares and/or coronal mass ejection (CME)-driven shocks can impose acute radiation hazards to space explorations. To measure energe…
Current sheets, plasmoids and flux ropes in the heliosphere. Part II: Theoretical aspects
O. Pezzi, F. Pecora, J. le Roux +13
Our understanding of processes occurring in the heliosphere historically began with reduced dimensionality - one-dimensional (1D) and two-dimensional (2D) sketches and models, whic…
Do All Interplanetary Coronal Mass Ejections Have A Magnetic Flux Rope Structure Near 1 AU?
Hongqiang Song, Jie Zhang, Xin Cheng +6
Interplanetary coronal mass ejections (ICMEs) often consist of a shock wave, sheath region, and ejecta region. The ejecta regions are divided into two broad classes: magnetic cloud…
Statistical analysis of interplanetary magnetic field path lengths from solar energetic electron events observed by WIND
Lulu Zhao, Gang Li, Ming Zhang +3
We calculate the interplanetary magnetic field path lengths traveled by electrons in solar electron events detected by the WIND 3DP instrument from to . The velocity d…
Is the enhancement of type II radio bursts during CME interactions related to the associated solar energetic particle event?
Liu-Guan Ding, Zhi-Wei Wang, Li Feng +2
We investigated 64 pairs of interacting-CME events identified by the simultaneous observations of SOHO and STEREO spacecraft from 2010 January to 2014 August, to examine the relati…
Probing the Puzzle of Behind-the-Limb -ray Flares: Data-driven Simulations of Magnetic Connectivity and CME-driven Shock Evolution
Meng Jin, Vahe Petrosian, Wei Liu +8
Recent detections of high-energy -rays from behind-the-limb (BTL) solar flares by the \emph{Fermi -ray Space Telescope} pose a puzzle and challenge on the particle accelerati…
Interchange reconnection associated with a confined filament eruption: Implications for the source of transient cold-dense plasma in solar winds
Ruisheng Zheng, Yao Chen, Bing Wang +1
The cold-dense plasma is occasionally detected in the solar wind with in situ data, but the source of the cold-dense plasma remains illusive. Interchange reconnections (IRs) betwee…
Observation of a Metric Type N Solar Radio Burst
Xiangliang Kong, Yao Chen, Shiwei Feng +7
Type III and type-III-like radio bursts are produced by energetic electron beams guided along coronal magnetic fields. As a variant of type III bursts, Type N bursts appear as the…
The injection of ten electron/He-rich SEP events
Linghua Wang, Säm Krucker, Glenn M. Mason +2
We have derived the particle injections at the Sun for ten good electron/He-rich solar energetic particle (SEP) events, using a 1.2 AU particle path length (suggested by anal…
On the identification of time interval threshold in the twin-CME scenario
Liu-Guan Ding, Gang Li, Li-Hua Dong +3
Recently it has been suggested that the "twin-CME" scenario Li.etal2012 may be a very effective mechanism in causing extreme Solar Energetic Particle (SEP) events and in particular…
Seed population in large Solar Energetic Particle events and the twin-CME scenario
Liu-Guan Ding, Gang Li, Gui-Ming Le +2
It has been recently suggested that large solar energetic particle (SEP) events are often caused by twin CMEs. In the twin-CME scenario, the preceding CME is to provide both an enh…
A Statistical Study of the Average Iron Charge Distributions inside Magnetic Clouds for Solar Cycle 23
Hongqiang Song, Ze Zhong, Yao Chen +5
Magnetic clouds (MCs) are the interplanetary counterpart of coronal magnetic flux ropes. They can provide valuable information to reveal the flux rope characteristics at their erup…
