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 ...

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.

Type‐III Solar Radio Bursts at Mars: A 16.5‐Year Catalog From Mars Express‐MARSIS at 0.1–5.5 MHz

Space Weather, Volume 24, Issue 10, October 2026.
Abstract The most intense radio feature in the Solar System are the solar Type‐III radio bursts, which are associated with electron beams that propagate along open magnetic field lines. Although solar radio bursts have been studied since the 1940s, observations remain mainly restricted within 1 AU.

Impact angle control of interplanetary shock geoeffectiveness [PDF]

Journal of Geophysical Research: Space Physics, 2014
AbstractWe use Open Geospace General Circulation Model global MHD simulations to study the nightside magnetospheric, magnetotail, and ionospheric responses to interplanetary (IP) fast forward shocks. Three cases are presented in this study: two inclined oblique shocks, hereafter IOS‐1 and IOS‐2, where the latter has a Mach number twice stronger than ...

Interplanetary Shocks Observed from Multipoints at Venus and 1 au

The Astrophysical Journal
We present a database of 12 fast forward interplanetary (IP) shocks observed in situ by radially aligned spacecraft (Venus Express, Wind, and/or STEREO) between 2006 and 2014.

Reconfiguration of Mercury's Exosphere During Strong Space Weather Events

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Mercury is exposed to various space weathering processes, which alter the surface and cause emission of atoms and molecules into the exosphere. The exosphere thus allows remote insights into the surface composition and erosion processes, with the emission of refractory elements such as Ca and Mg typically being dominated by micrometeoroid ...

IMF By‐Controlled Dawn–Dusk and Hemispheric Asymmetries of Kelvin–Helmholtz Waves and Reconnection Geometry Under Negative Dipole Tilt

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Along with magnetic reconnection, Kelvin‐Helmholtz (KH) waves are the main mechanisms controlling the solar wind‐magnetosphere interaction, enabling plasma transport into the magnetosphere due to secondary reconnection, diffusion and wave‐particle interactions.

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.

The Evolution of Autonomous Systems for Planetary Cave Exploration: A Review

Journal of Field Robotics, Volume 43, Issue 6, Page 4094-4115, September 2026.
ABSTRACT The exploration of Subsurface Access Points (SAPs), such as lava tubes on the Moon and Mars, has gained significant interest due to their potential as stable environments shielded from surface radiation and temperature extremes. These sites are considered high‐value targets for detecting water and signs of ancient life, and assessing their ...

Numerical Investigations of Low‐Latitude Ground Magnetic Fields Due To Cavity Mode Oscillations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract Pi2 oscillations are known to be associated with cavity mode oscillations (CMOs) in the inner magnetosphere at low latitudes. CMOs can also be excited by interplanetary shocks on the dayside. We present results from a global linear MHD wave model in spherical coordinates that allows us to analyze these waves at equatorial latitudes.
