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.

The Effects of ICME Composition on the Sputtered Component of the Lunar Exosphere

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Charged‐particle sputtering is a fundamental process that contributes to the generation of the Moon’s neutral exosphere. Neutral sputtering rates are dependent on the speed, flux, and composition of the incident charged‐particle populations, all of which are variable at the Moon’s orbit.

Ionospheric Mechanisms Leading to Plasma‐Bubble Zonal Drift Reversal and Deformation During the 12 November 2025 Geomagnetic Storm

Space Weather, Volume 24, Issue 10, October 2026.
Abstract We present a multi‐instrument analysis of the ionospheric response to the intense geomagnetic storm of 12 November 2025 over the American sector, with emphasis on the longitudinally asymmetric deformation, latitudinal expansion, and zonal drift reversal of equatorial plasma bubbles (EPBs).

Correlation of Diffusion Upstream of Shocks with Their Magnetic Compression: An Application of IMAP’s Living Catalog of Interplanetary Shocks

The Astrophysical Journal Supplement Series
We apply an automated routine to detect and catalog interplanetary shocks observed by the Interstellar Mapping and Acceleration Probe (IMAP). Using this catalog, we derive the upstream diffusion coefficient corresponding to 1 MeV protons along each shock’

The θBn problem: Determination of local magnetic parameters of interplanetary shocks from in situ IMF data [PDF]

Geofísica Internacional, 2001
The angle θBn is the angle between the upstream magnetic field and the shock normal direction and is important for many phenomena in interplanetary physics.

Integrated Digital Garment Modeling and Monte Carlo Simulation of a Water‐Based Radiation Protection Vest for Spaceflight Radiation Hazards

Space Weather, Volume 24, Issue 10, October 2026.
Abstract As crewed space missions set course for the Moon and beyond, astronauts will experience prolonged exposure to Galactic Cosmic Rays (GCR) and potentially intense Solar Proton Events (SPEs), both of which pose significant short‐ and long‐term health risks.

Finding Novel Precursors for Solar Wind Stream Interaction Regions With Interpretable Deep Learning

Space Weather, Volume 24, Issue 10, October 2026.
Abstract Solar wind stream interaction regions (SIRs) drive recurrent geomagnetic storms, yet most existing catalogs rely on expert inspection and simple thresholds that are subjective and can miss events with complex morphologies. We present SIREN (SIR Encoder Network), a lightweight Transformer‐based model for per‐timestep SIR detection from in situ ...

Modification of the Power Spectral Density of Magnetic Field Fluctuations by Quasi-perpendicular Interplanetary Shocks

The Astrophysical Journal Letters
We investigate the role of interplanetary (IP) shocks in solar wind turbulence using observations of Solar Orbiter, Parker Solar Probe, and Wind. Employing statistical analysis of quasi-perpendicular fast forward (FF) and fast reverse (FR) shocks, we ...

Low Density Drivers of Strong Interplanetary Shocks [PDF]

International Astronomical Union Colloquium, 1996
AbstractThe theory that most, if not all, interplanetary shocks are caused by coronal mass ejections (CMEs) faces serious problems in accounting for the strongest shocks. The difficulties include (i) a remarkable absence of very strong shocks during solar maximum 1980 when CMEs were prolific, (ii) unrealistic initial speeds near the Sun for impulsive ...

MP‐DualNet: A Dual‐Branch Deep Learning Approach for Magnetopause Boundary Detection Using Simulated SXI Images

Space Weather, Volume 24, Issue 10, October 2026.
Abstract The Earth's magnetopause is a key boundary governing solar wind–magnetosphere coupling. The Solar wind Magnetosphere Ionosphere Link Explorer (SMILE) mission will provide global soft X‐ray imaging of the magnetosphere through solar wind charge exchange (SWCX) emission, offering a new opportunity for remote sensing of magnetopause dynamics ...
