Earthward O+ Injections in the Plasma Sheet Boundary Layer During Geomagnetic Storms

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract During geomagnetic storms, energetic ions are injected from the Earth's magnetotail along the plasma sheet boundary layer (PSBL). Owing to its off‐equatorial inclined orbit, the Arase satellite is in a prime position to observe these injections in the PSBL on the nightside at the apogee.

Auroral signatures of ionosphere-magnetosphere coupling at Jupiter and Saturn

open access: yes, 2012
Planetary auroral emissions are an observable signature of the coupling between the planetary magnetosphere and ionosphere. Jovian and Saturnian auroral emissions are created by a variety of processes, including those driven by the orbital motions of ...

Planetary-period oscillations in Saturn’s magnetosphere

open access: yes, 2011
This thesis is concerned with the study of near-planetary rotation period oscillations in Saturn’s magnetic field. Similar oscillations are present in a variety of other magnetospheric phenomena, most notably kilometre-wavelength radio emissions, and ...

Solar Wind–Magnetosphere Coupling by the Kelvin–Helmholtz Instability at Mercury

open access: yesThe Astrophysical Journal
The Kelvin–Helmholtz instability (KHI) has been considered important in the energy transfer and momentum coupling between the solar wind and planetary magnetospheres.

Statistical Mapping of ULF Wave Power in the Vicinity of Earth's Bow Shock Using Cluster Magnetic Field Data

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract Ultra‐low frequency (ULF) waves with frequencies 10–140 s are a characteristic feature of the foreshock, playing important roles in transient formation, shock reformation, and particle acceleration. We utilize 23 years of Cluster data to map ULF wave power and compressibility in the vicinity of Earth's bow shock, combining Cluster data with ...

Europa's Neutral Sodium Exosphere Is Quasi‐Stable Over Decades

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract Europa's sodium cloud is thought to be modified by its orbital longitude and by its plasma environment, which modulates with Jovian magnetic geometry. To explore and quantify sodium cloud variability, seven sets of Keck I/HIRES measurements are compared providing comprehensive coverage of orbital and magnetic geometry.

Escape of planetary ions from Mercurys magnetosphere under different solar wind conditions

open access: yes, 2021
International audienceThe combination of a weak intrinsic magnetic field and strong solar wind conditions at Mercury results in the formation of a relatively small magnetosphere compared to that of the Earth.

Magnetic Field and Plasma Asymmetries Between the Martian Quasi‐Perpendicular and Quasi‐Parallel Magnetosheaths

open access: yesGeophysical Research Letters
The Martian magnetosheath acts as a conduit for mass and energy transfer between the upstream solar wind and its induced magnetosphere. However, our understanding of its global properties remains limited. Using 9 years of data from NASA's Mars Atmosphere

Response of Thermospheric Nitric Oxide (NO) Cooling During Events of Strong Solar Wind Pressure

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract Nitric oxide (NO) infrared emissions are a notable indicator for varying thermospheric energy budget during geomagnetic storms while the Interplanetary Magnetic Field (IMF) is southward. In this study, we present the first investigation on the response of NO cooling emissions during northward IMF conditions.

Faint Diffuse 557.7‐nm Emissions Equatorward of the Auroral Oval: Conjugate Observations by Ground Airglow Imagers and the Arase Satellite

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract At subauroral latitudes, discrete auroras, such as strong thermal emission velocity enhancement and stable auroral red arcs, have been extensively studied. On the other hand, diffuse emissions at subauroral latitudes have not been studied well.
