Ion Inverted‐V Precipitation Adjoining Auroral Arc: Low‐Altitude Observations With High Time/Space Resolution by the Reimei Microsatellite

Geophysical Research Letters, Volume 52, Issue 5, 16 March 2025.
Abstract Previous studies have verified that upward geomagnetic field‐aligned electric fields (FAEFs) produce inverted‐V signatures of precipitating electrons that generate discrete auroras in upward field‐aligned currents (FACs). However, clear ion inverted‐V signatures have rarely been reported in the polar magnetosphere.

Ray Tracing of Whistler Mode Waves in Jupiter's Magnetosphere

Geophysical Research Letters, Volume 52, Issue 5, 16 March 2025.
Abstract Previous statistical studies have described the distributions and properties of whistler‐mode waves in Jupiter's magnetosphere, but explaining these wave distributions requires modeling wave propagation from their generation near the magnetic equator.

Bifurcation of Jovian magnetotail current sheet [PDF]

Annales Geophysicae, 2006
Multiple crossings of the magnetotail current sheet by a single spacecraft give the possibility to distinguish between two types of electric current density distribution: single-peaked (Harris type current layer) and double-peaked (bifurcated current ...

A pair of Jovian Trojans at the L4 Lagrange point [PDF]

, 2020
Asteroid pairs, two objects that are not gravitationally bound to one another, but share a common origin, have been discovered in the Main belt and Hungaria populations. Such pairs are of major interest, as the study of their evolution under a variety of dynamical influences can indicate the time since the pair was created.

Ion Phase Space Density Profiles Within the Magnetosphere of Saturn: Investigating the Source of Suprathermal Ions

Journal of Geophysical Research: Space Physics, Volume 130, Issue 3, March 2025.
Abstract Phase space density (PSD) profiles at fixed values of the first two adiabatic invariants (μ ${\upmu }$; magnetic moment and k $k$; longitudinal invariant) versus L shell provide a quantitative way to investigate the sources, losses, and radial transport of plasma and energetic charged particles within a planetary magnetosphere.

The Lense–Thirring Effect on the Galilean Moons of Jupiter

Universe, 2023
The perspectives of detecting the general relativistic gravitomagnetic Lense–Thirring effect on the orbits of the Galilean moons of Jupiter induced by the angular momentum S of the latter are preliminarily investigated.

MESSENGER Observations of a Possible Alfvén Wing at Mercury Driven by a Low Alfvénic Mach Number Interplanetary Coronal Mass Ejection

Journal of Geophysical Research: Space Physics, Volume 130, Issue 3, March 2025.
Abstract We investigate Mercury's response to rare, low Alfvénic Mach number MA $\left({M}_{A}\right)$ solar wind conditions using observations from the Mercury Surface, Space Environment, Geochemistry, and Ranging (MESSENGER) mission. This study provides compelling evidence of Mercury's altered magnetospheric state under these extreme conditions ...

Spatially Resolved Visible Wavelength Spectroscopy of the Galilean Moons With VLT/MUSE

Journal of Geophysical Research: Planets, Volume 130, Issue 3, March 2025.
Abstract We present observations of all four Galilean satellites using spatially resolved visible wavelength (475–935 nm) spectroscopic observations with the ground‐based VLT/MUSE + AOF facility in 2019. A range of features in the observed reflectance spectra were compared to laboratory measured spectra, and mapped to understand the spatial ...

Jovian Electrons in the Inner Heliosphere: Opportunities for Multi-spacecraft Observations and Modeling

The Astrophysical Journal
In this paper we explore the idea of using multi-spacecraft observations of Jovian electrons to measure the 3D distribution of these particles in the inner heliosphere.

Stratigraphy, Crater Size–Frequency Distribution, and Chronology of Selected Areas of Ganymede’s Light and Dark Terrains

The Planetary Science Journal, 2023
The stratigraphy of the largest natural satellite of our solar system, Ganymede, is investigated using available global mosaic (basemap) and high-resolution images. We are focusing on the reconstruction of the formation and tectonic evolution of selected
