Corotating drift-bounce resonance of plasmaspheric electron with poloidal ULF waves

Earth and Planetary Physics, 2017
The purpose of this paper is to understand how low energy plasmaspheric electrons respond to ULF waves excited by interplanetary shocks impinging on magnetosphere. It is found that both energy and pitch angle dispersed plasmaspheric electrons with energy

Variations of Heavy Ions in Different Types of Interplanetary Shocks

The Astrophysical Journal
Heavy ions upstream and downstream of interplanetary shocks are not only subject to acceleration, heating, and spatiotemporal modulation during their propagation in interplanetary space, but they can also, in turn, influence the dynamical properties of ...

Evidence for superdiffusive shock acceleration at interplanetary shock waves

Journal of Physics: Conference Series, 2015
Recent analysis of time profiles of energetic particles accelerated at interplanetary shocks has shown evidence for superdiffusive transport upstream of the shock fronts, namely for a transport characterized by a particle mean square displacement that grows faster than linearly in time.

Spectral Evolution of Pickup Ions across Interplanetary Shocks in the Outer Heliosphere: Observational Constraints and Transport Simulations

The Astrophysical Journal Letters
Pickup ions (PUIs) often experience acceleration and heating as they traverse interplanetary shocks, leading to the formation of a distinct suprathermal tail in their energy spectra downstream of the shock.

Modelling large solar proton events with the shock-and-particle model

Journal of Space Weather and Space Climate, 2015
We have developed a new version of a model that combines a two-dimensional Sun-to-Earth magnetohydrodynamic (MHD) simulation of the propagation of a CME-driven shock and a simulation of the transport of particles along the interplanetary magnetic field ...

Evolution of Electron Acceleration by Corotating Interaction Region Shocks at 1 au

The Astrophysical Journal Letters
We present the first observations of in situ electron acceleration at corotating interaction region (CIR) shocks near 1 au, utilizing measurements from Wind and Magnetospheric Multiscale (MMS) mission in the interplanetary medium. As the forward (reverse)

Interplanetary shock induced intensification of electron cyclotron harmonic waves in the Earth’s inner magnetosphere

Frontiers in Physics
Electron cyclotron harmonic (ECH) waves are electrostatic emissions frequently observed in the Earth’s magnetosphere. By precipitating magnetospheric hot electrons into the ionosphere, ECH waves play a critical role in the formation of diffuse aurora ...

Shock-induced magnetic reconnection in the Venusian magnetotail

Nature Communications
Magnetic reconnection, a universal process governing energy release in astrophysical plasmas, has long been studied as a key phenomenon in magnetized planets. However, its drivers and impacts in unmagnetized bodies remain poorly understood.
