Relationship of transport coefficients with statistical quantities of charged particles
J. F. Wang, G. Qin
In the previous studies, from the Fokker-Planck equation the general spatial transport equation, which contains an infinite number of spatial derivative terms $T_n=κ_{nz}\partial^n…
Perpendicular diffusion coefficient of cosmic rays in the presence of weak adiabatic focusing
J. F. Wang, G. Qin, Q. M. Ma +2
The influence of adiabatic focusing on particle diffusion is an important topic in astrophysics and plasma physics. In the past several authors have explored the influence of along…
Numerical simulations of solar energetic particle event timescales associated with ICMES
S. -Y. Qi, G. Qin, Y. Wang
Recently, S.W. Kahler studied the solar energetic particle (SEP) event timescales associated with coronal mass ejections (CMEs) from spacecraft data analysis. They obtained differe…
Simulations of a gradual solar energetic particle event observed by Helios 1, Helios 2, and IMP 8
G. Qin, Y. Wang
In this work, a gradual solar energetic particle (SEP) event observed by multispacecraft has been simulated. The time profiles of SEP fluxes accelerated by an interplanetary shock…
Simulations of the spatial and temporal invariance in the spectra of gradual solar energetic particle events
Yang Wang, Gang Qin
The spatial and temporal invariance in the spectra of energetic particles in the gradual solar events is reproduced in the simulations. Based on a numerical solution of the focused…
Study of Different Solar Cycle Variations of Solar Energetic Particles and Cosmic Rays by Despiking ACE/SIS Heavy-Ion Fluxes
G Qin, L. -L. Zhao
Cosmic Rays (CRs) include Galactic Cosmic Rays (GCRs) and Anomalous Cosmic Rays (ACRs). The CR flux data of protons and heavy-ions observed with spacecraft are often seriously cont…
Estimation of the release time of solar energetic particles near the Sun
Y. Wang, G. Qin
This paper investigates the onset time of Solar Energetic Particle (SEP) events with numerical simulations, and analyses the accuracy of the Velocity Dispersion Analysis (VDA) meth…
