Length, Width, and Relative Age Analysis of Lineaments in the Galileo Regional Maps with LineaMapper

The Planetary Science Journal
The Galileo regional mosaics (“RegMaps”) show Europa’s extensive regional-scale tectonic features under similar illumination conditions. Detailed lineament studies can help constrain resurfacing events and formation mechanisms, but most lineament maps ...

Coincident ENA and Narrowband Radio Emissions as Diagnostics of Inward Plasma Transport at Saturn

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Saturn's kilometric radiation (SKR) and Energetic Neutral Atom (ENA) emissions are important diagnostics of the planet's magnetospheric dynamics, intensifying during global plasma injections and displaying characteristic planetary periodicity. Related to the SKR emissions are myriametric narrowband radio emissions that typically appear in the ...

Jovian Auroral Proton Precipitation

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract The total power of the Jovian aurora is about 1013–1014 W with ultraviolet emission observed in the Lyman and Werner bands of molecular hydrogen. X‐ray, radio, and infrared emissions have also been observed. The Jovian Auroral Distributions Experiment and the Jovian Energetic Particle Detector Instrument onboard the Juno spacecraft, orbiting ...

Ice-Ocean Exchange Processes in the Jovian and Saturnian Satellites

Space Science Reviews, 2020
A growing number of satellites in the outer solar system likely have global oceans beneath their outer icy shells. While the presence of liquid water makes these ocean worlds compelling astrobiological targets, the exchange of heat and materials between the deep interior and the surface also plays a critical role in promoting habitable environments. In

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 ...

Reconstructing Europa's Atmosphere From H2+ ${\mathbf{H}}_{\mathbf{2}}^{+}$ Pickup Ions Detected During the Juno PJ45 Flyby

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract We use a suite of single‐species (H2 ${\mathrm{H}}_{2}$) and multispecies (H2+O2+H+O ${\mathrm{H}}_{2}+{\mathrm{O}}_{2}+\mathrm{H}+\mathrm{O}$) Direct Simulation Monte Carlo models of Europa's atmosphere to interpret the H2+ ${\mathrm{H}}_{2}^{+}$ pickup ions detected by Juno at distances beyond 2 $2$ Europa radii RE $\left({R}_{E}\right ...

The long-term dynamics of the Jovian irregular satellites [PDF]

Astronomy & Astrophysics, 2011
Context. The dynamical region of the Jovian irregular satellites presents an interesting web of resonances that are not yet fully understood. Of particular interest is the influence of the resonances on the stochasticity of the individual orbits of the satellites, as well as on the long-term chaotic diffusion of the different families of satellites ...

Dawn–Dusk Asymmetry of the Io Plasma Torus Derived from Io’s Auroral Footprints Observed by Juno-UVS

The Planetary Science Journal
The Io plasma torus (IPT) is a dense plasma cloud that corotates around Jupiter near Io’s orbit. A dawn-to-dusk electric field shifts the IPT dawnward.

Temporal Variations of Jupiter's Plasma Disk Observed by Juno

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract In Jupiter's magnetosphere, a key question is how plasma is transported outward from its source near Io to the distant magnetotail. Since 2016, the plasma disk has been extensively observed by the Juno mission. Using plasma data from the JADE instrument, we perform an analysis revealing significant temporal variation. For different Juno orbits,

JWST Reveals Varied Origins between Jupiter’s Irregular Satellites

The Planetary Science Journal
We report JWST NIRSpec (0.7–5.1 μ m) observations of eight Jovian irregular satellites across five orbital groups. We detect variation in the phyllosilicate content of the three largest members of the Himalia collisional family (Himalia, D  ∼ 140 km ...
