An Inversion of Magnetic Field Measurements to Constrain the Depth, Thickness, and Conductivity of Europa's Ocean

Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract The Galilean satellite Europa is a primary candidate for the study of ocean worlds. In anticipation of NASA's Europa Clipper and ESA's JUICE missions, we revisit the magnetic field measurements of the Galileo spacecraft. The ocean's induction response is governed by its induction amplitude and phase shift, which are a function of the ocean ...

Drifting discrete Jovian radio bursts reveal acceleration processes related to Ganymede and the main aurora

Nature Communications, 2023
Radio detection at high time-frequency resolutions is a powerful means of remotely studying electron acceleration processes. Radio bursts have characteristics (polarization, drift, periodicity) making them easier to detect than slowly variable emissions.

Antum Crater: A Window Into Ganymede's Icy Evolution

Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract Located within the extensive dark terrain of Marius Regio, in the anti‐Jovian trailing quadrant of Ganymede, Antum crater is marked by dark‐rayed ejecta that obscure older features and reshape the surrounding landscape. This study investigates Antum and its geological context using optical and infrared data from the Voyager and Galileo ...

Statistical Distributions of Plasma Density and Pressure in the Jovian Plasma Sheet

The Astrophysical Journal
The Jovian plasma sheet is a key region of the Jovian magnetosphere populated by a mix of warm and hot plasma. It is the main channel for radial transport of mass and energy in the Jovian magnetosphere and provides a favorable environment for magnetic ...

Investigating the Occurrence of Magnetic Reconnection at Jupiter's Dawn Magnetopause During the Juno Era

Geophysical Research Letters, 2022
In this study, observations from the Jovian auroral distributions experiment, Jupiter energetic particle detector instrument, and Magnetic field investigation instruments on Juno are used to identify signatures of magnetic reconnection at Jupiter's dawn ...

On the Equation of State in Jovian Seismology [PDF]

International Astronomical Union Colloquium, 1994
AbstractWe have investigated the effect on the seismological properties of the giant planet Jupiter of different descriptions of the equation of state (EOS) of the fluid hydrogen helium envelop. Recent Jovian models by Chabrier et al. 1992 use the equation of state of Saumon et al. (1992) which predicts the PPT (plasma phase transition).

Whistler‐Mode Waves and Associated Electron Distributions in Jupiter's Middle and Outer Magnetosphere

Geophysical Research Letters, Volume 52, Issue 18, 28 September 2025.
Abstract Whistler‐mode waves play a crucial role in shaping magnetospheric electron dynamics. Using Juno's observations, we investigate these waves in Jupiter's post‐midnight‐to‐dawn magnetosphere, spanning 20–80 Jupiter radii. Our survey reveals that whistler‐mode waves predominantly occur in the lobes, while the magnetodisk remains largely devoid of ...

Detection of Negative Carbon and Oxygen Pickup Ions From Dust Orbiting Jupiter

Geophysical Research Letters, Volume 52, Issue 18, 28 September 2025.
Abstract We report on observations of negative carbon and oxygen pickup ions (PUIs) originating from dust orbiting Jupiter. The PUIs are observed at altitudes of a few thousand kilometers (∼4,800–10,200 km) above the 1‐bar level of Jupiter's atmosphere and up to ∼11,000–15,000 km from the equatorial plane, thus providing constraints on the location of ...

Radial Evolution of Electron Pitch Angle Distributions in the Inner Part of Jovian Magnetosphere

Geophysical Research Letters, Volume 52, Issue 17, 16 September 2025.
Abstract Previous observations in Jupiter's magnetosphere have revealed that the pitch‐angle distributions (PADs) of energetic (>∼102 ${ >} \sim 1{0}^{2}$ keV) electrons transition from pancake to field‐aligned distributions from ∼ ${\sim} $10 to 20 Jupiter radii.
