Statistical Analysis of the Equatorward UV Auroral Emissions of the Jovian Southern Hemisphere

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract This study presents a comprehensive statistical analysis of Jupiter's southern UV auroral emissions, with a focus on the secondary oval and equatorward injection signatures. Utilizing Hubble Space Telescope (HST) data, the frequency, location, and intensity of these auroral features are systematically evaluated, considering their variation ...

Delivery of Dust Particles from Protoplanetary Disks onto Circumplanetary Disks of Giant Planets

The Astrophysical Journal
The principal regular satellites of gas giants are thought to be formed by the accumulation of solid materials in circumplanetary disks (CPDs). While there has been significant progress in the study of satellite formation in CPDs, details of the supply ...

Propagation Dynamics of Fast Electron Beam and Its Electron Cyclotron Maser Emission

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract Fast electron beams (FEBs) and coherent radio bursts both are very common plasma activity phenomena in the cosmos. The electron cyclotron maser (ECM) instability driven by FEBs trapped in magnetic fields can directly amplify radio wave radiations.

New Global Map of Io’s Volcanic Thermal Emission and Discovery of Hemispherical Dichotomies

The Planetary Science Journal
By combining multiple spacecraft and telescope data sets, the first fully global volcanic heat flow map of Io has been created, incorporating data down to spatial resolutions of ∼10 km pixel ^−1 in Io’s polar regions.

A Mechanism for the Generation of Enhanced Fluxes at Discrete Energies on the Wakes of the Galilean Moons

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract In this study, we propose a new mechanism to explain the observed particle flux at discrete energies in the flux tubes connecting to the wakes of the Galilean moons, first reported by Sarkango et al. (2024, https://doi.org/10.1029/2023gl107431) and referred to as “banded flux.” We demonstrate the proposed mechanism using test particle ...

Hot Spot Detections and Volcanic Changes on Io during the Juno Epoch: Orbits PJ5 to PJ55

The Planetary Science Journal
We report volcanic changes on Io since the last Galileo (2002) and New Horizons (2007) flybys as observed by NASA’s Juno spacecraft, examining Io’s volcanism down to the local scale (200 K at 325 individual sites of volcanic activity has been generated ...

Not just gas: How solids-driven torques shaped the migration of the Galilean moons

Astronomy & Astrophysics
Context. A crucial aspect of formation models for the Galilean moons of Jupiter is that the objects survive rapid inward orbital migration. Aims. The primary aim of this study is to investigate the orbital migration of the Galilean moons by incorporating

Plasma Properties at the Orbits of Ganymede and Callisto: Survey of Juno Data

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract The space environment around the Galilean moons is important for understanding the interaction of the magnetospheric plasma with their magnetosphere (in the singular case of Ganymede), their atmospheres and surfaces. Juno's orbital evolution brought the spacecraft close to the orbits of Ganymede and Callisto on multiple occasions over several ...
