Three-stage Acceleration of Solar Energetic Particles Detected by Parker Solar Probe

The Astrophysical Journal Letters
Coronal mass ejections (CMEs) drive powerful shocks and thereby accelerate solar energetic particles (SEPs) as they propagate from the corona into interplanetary space.

Earthward Transport of Lunar Metallic Ions: Implications of Heavy Ions in the Magnetosphere

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract Low‐charge‐state heavy ions in Earth's magnetosphere were thought to originate from the ionosphere. However, Observations from the Geotail mission have detected the presence of singly charged metallic ions, such as Fe+ ${\mathrm{F}\mathrm{e}}^{+}$, whose abundances vary depending on the Moon's location, alongside their density ratios to O ...

Impacts of Neutral Wind‐Driven Currents on Geomagnetic Disturbances and Magnetospheric Dynamics During the May 2024 Storm

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract The neutral wind dynamo generates ionospheric currents that can significantly affect high‐latitude electrodynamics during geomagnetic storms, yet its role in global magnetosphere‐ionosphere coupling is often underrepresented. We quantify the impact of wind‐driven currents on geomagnetic disturbances (GMDs) and magnetospheric dynamics during ...

Propagation of Interplanetary Shocks in the Heliosphere

, 2023
Interplanetary shocks are one of the crucial dynamic processes in the Heliosphere. They accelerate particles into a high energy, generate plasma waves, and could potentially trigger geomagnetic storms in the terrestrial magnetosphere disturbing significantly our technological infrastructures. In this study, two IP shock events are selected to study the

Uranus's Highly Nonaxisymmetric Magnetopause and Its Impact on Magnetic Reconnection

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract Mass and energy fluxes from the solar wind can access a planet's magnetosphere through dayside magnetic reconnection. The plasma and magnetic field conditions on either side of the magnetopause determine whether reconnection is suppressed. However, magnetosheath conditions are sensitive to the shape of the magnetopause, and deviations from ...

Characterization of CME-driven shock in the interplanetary medium using type II radio bursts [PDF]

, 2017
Type II radio bursts are indirect signatures of the fast magnetosonic shock formation in the heliosphere. Those types of MHD shocks accelerate electron beams that via plasma emission mechanism produce electromagnetic radiation.

Global Characterization of the Compressional Components of Magnetic Wave Activity in Mercury's Foreshock Region

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract Mercury's weak intrinsic magnetic field forms a small magnetosphere and thus a bow shock that decelerates the supermagnetosonic solar wind and reflects particles upstream, forming a foreshock in the quasi‐parallel region. This region is populated by backstreaming ions and electrons and associated wave activity.

Computations on the interaction of an interplanetary shock with the Earth's magnetosphere

Astrophysics and Space Science, 1977
We present the results of a one-dimensional computer simulation of the interaction between interplanetary shocks and the Earth's magnetosphere. The position of the bowshock as a function of solar wind velocity and interplanetary field direction is studied.
