Solar interacting protons versus interplanetary protons in the core plus halo model of diffusive shock acceleration and stochastic re-acceleration [PDF]

, 2015
With the first observations of solar γ-rays from the decay of pions, the relationship of protons producing ground level enhancements (GLEs) on the Earth to those of similar energies producing the γ-rays on the Sun has been debated.

Superposition of Doppler‐Shifting Magnetopause Kelvin‐Helmholtz Modes Through Dynamic Mode Decomposition of a Global MHD Simulation

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract The Kelvin‐Helmholtz instability (KHI) mediates the viscous‐like solar‐terrestrial interaction by generating magnetopause surface waves that quickly become non‐linear. Basic theory predicts the locally most‐unstable linear wave dominates.

Acceleration of Solar Wind Ions by Nearby Interplanetary Shocks: Comparison of Monte Carlo Simulations with Ulysses Observations [PDF]

, 1996
The most stringent test of theoretical models of the first-order Fermi mechanism at collisionless astrophysical shocks is a comparison of the theoretical predictions with observational data on particle populations.

Electrostatic Plasma Wave Excitations at the Interplanetary Shocks

The Astrophysical Journal, 2023
Abstract Over the last few decades, different types of plasma waves (e.g., the ion acoustic waves (IAWs), electrostatic solitary waves, upper/lower hybrid waves, and Langmuir waves) have been observed in the upstream, downstream, and ramp regions of the collisionless interplanetary (IP) shocks.

LEO‐DOS Absorbed Dose Observations During the May 2024 Geomagnetic Superstorm

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract The Low‐Earth Orbit Space Radiation Dosimeter (LEO‐DOS) onboard Next‐Generation Satellite II (NEXTSat‐2) measured absorbed dose rate variations during the May 2024 geomagnetic superstorm. The observations show deep storm‐time penetration of solar energetic particle (SEP) spanning L ≈ 2–10, a pronounced enhancement near L ≈ 3 consistent with ...

Large‐Scale Magnetosheath Jets Formed by Shock‐Discontinuity Interactions: A Three‐Dimensional Global Hybrid Simulation

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Magnetosheath high‐speed jets with enhanced dynamic pressure are common in Earth's magnetosheath and can impinge on the magnetopause, driving pronounced boundary deformation. Recent observations indicate that shock–discontinuity interactions (SDIs) can generate magnetosheath jets, but the formation mechanism is still unclear.

Simulations of Electron Acceleration at Collisionless Shocks: The Effects of Surface Fluctuations [PDF]

, 2006
Energetic electrons are a common feature of interplanetary shocks and planetary bow shocks, and they are invoked as a key component of models of nonthermal radio emission, such as solar radio bursts.

Soft X‐Ray Emission From Saturn's Magnetosheath Part I: 3D Modeling From MHD Data

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract Saturn's magnetosheath hosts a mixed population of water‐group neutrals and solar wind plasma. We present a 3‐D model of soft X‐ray emission by ion‐neutral charge exchange in the near‐equatorial magnetosheath. The model employs MHD simulation data of plasma properties at Saturn, Enceladus‐genic neutral populations extrapolated from existing ...

A case study of large-amplitude ULF waves in the Martian foreshock

Earth and Planetary Physics, 2020
Foreshock ultralow frequency (ULF) waves constitute a significant physical phenomenon in the plasma environment of terrestrial planets. The occurrence of these waves, associated with backstreaming particles reflected and accelerated at the bow shock ...
