The acceleration and transport of energetic electrons during solar flares is one of the
outstanding topics in solar physics. Recent X-ray and radio imaging and spectroscopy …

Two recent extremely fast coronal mass ejections (CMEs) are of particular interest. The first
one originated from the southern hemisphere on 2021 October 28 and caused strong solar …

Aims. We study how a fast solar wind stream embedded in a slow solar wind influences the
spread of solar energetic protons in interplanetary space. In particular, we aim at …

We present a new three-dimensional (3D) magnetohydrodynamic (MHD) model and a new
3D energetic particle transport (EPT) model. The 3D MHD model numerically solves the …

Aims. An energetic particle event related to a corotating interaction region (CIR) structure
was observed by the Solar-Terrestrial Relations Observatory-A (STEREO-A) from 21 to 24 …

The anisotropy of energetic particles provides essential information to help resolve the
underlying fundamental physics of their spatial distributions, injection, acceleration, and …

Three-dimensional (3-d) magnetohydrodynamics (MHD) modeling is a key method for
studying the interplanetary solar wind. In this paper, we introduce a new 3-d MHD solar wind …

We extend a recently published analytic model for the intensity–time profile of solar
energetic particle (SEP) events, in which the dominant physical mechanism is turbulent pitch …

We present an analytic model for the intensity-time profile of solar energetic particle events,
based on considerations related to the delay-time distribution that results from interplanetary …

The effect of a tilted-dipole three-dimensional corotating interaction region (CIR) on the
transport and acceleration of solar energetic particles (SEPs) is studied. In this work, we …
