Europa is Embedded in Non‐Maxwellian, Anisotropic Electron Distributions

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract In September 2022, the Juno spacecraft flew by Europa, providing new insight into the electron pitch angle and energy distributions via the Jovian Auroral Distributions Experiment electron analyzers (JADE‐E). We fit these observations with two anisotropic kappa distributions (cold and hot), accounting for spacecraft potential, which we find to

Capturing Trojans and Irregular Satellites - the key required to unlock planetary migration [PDF]

, 2013
It is now accepted that the Solar system's youth was a dynamic and chaotic time. The giant planets migrated significant distances to reach their current locations, and evidence of that migration's influence on the Solar system abounds.

Giant impacts in the Saturnian System: a possible origin of diversity in the inner mid-sized satellites

, 2011
It is widely accepted that Titan and the mid-sized regular satellites around Saturn were formed in the circum-Saturn disk. Thus, if these mid-sized satellites were simply accreted by collisions of similar ice-rock satellitesimals in the disk, the ...

A Multifrequency Global View of Callisto’s Thermal Properties from ALMA

The Planetary Science Journal
We present thermal observations of Callisto’s leading and trailing hemispheres obtained using the Atacama Large Millimeter/submillimeter Array (ALMA) at 0.87 mm (343 GHz), 1.3 mm (233 GHz), and 3 mm (97 GHz).

Short‐Term Variability of Jupiter's Satellite Footprints as Spotted by JWST

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract We present the main Alfvén wing (MAW) spots of Io and Europa as observed by the Near‐Infrared Spectrograph onboard the James Webb Space Telescope. These auroral footprint features have been measured previously, but only in emission. Here, the derived ionospheric H3+ ${\mathrm{H}}_{3}^{+}$ emission, temperature and column density are reported ...

N-body Simulations of Satellite Formation around Giant Planets: Origin of Orbital Configuration of the Galilean Moons

, 2012
As the number of discovered extrasolar planets has been increasing, diversity of planetary systems requires studies of new formation scenarios. It is important to study satellite formation in circumplanetary disks, which is often viewed as analogous to ...

Revealing Callisto’s Near-subsurface Thermophysical Properties with ALMA Calibration Data

The Planetary Science Journal
Thermal images at different wavelengths probe varying subsurface depths of planetary bodies and therefore can inform us about their compositions, thermophysical properties, and impact histories.

Modeling the EMIC Wave‐Induced Acceleration of Energetic Protons in the Io Footprint Tail

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract The Io footprint tail (FPT) region is crucial for studying the interactions between Io and Jupiter's magnetosphere. In this region, Juno spacecraft observed significant acceleration of energetic protons, concurrently with electromagnetic ion cyclotron (EMIC) waves below the proton gyro‐frequency.

An Investigation on the Apparent North‐South Asymmetry Identified in Multiple Current Sheet Crossing Events in Jovian Dawn Outer Magnetosphere

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Jovian magnetospheric dynamics are often believed to be mainly controlled by internal elements such as Jupiter's strong and fast‐rotating magnetic moment and Io's abundant volcanic escape, as these internal elements are powerful enough to control the magnetospheric dynamics, contrary to the internal elements of the earth's magnetosphere.

Tidal Response of Preliminary Jupiter Model

, 2016
In anticipation of improved observational data for Jupiter's gravitational field from the Juno spacecraft, we predict the static tidal response for a variety of Jupiter interior models based on ab initio computer simulations of hydrogen-helium mixtures ...
