A scenario for Jovian S‐bursts

Geophysical Research Letters, 1996
Jovian S‐bursts are intense impulsive decameter radio spikes drifting in frequency in tens of milliseconds over several hundreds of kHz up to a few MHz. Their generation scenario has been much debated for 30 years. The automated analysis of an extensive set of digital radio observations at very high temporal and spectral resolutions is presented here ...

Statistical Study on L‐O Mode Saturn Kilometric Radiation

Geophysical Research Letters, Volume 52, Issue 15, 16 August 2025.
Abstract Based on the 13 years‐long observation of Saturn kilometric radiation (SKR) by the Cassini/Radio and Plasma Wave Science instrument, this study derives statistics for left‐hand (L‐O) mode SKR emissions. These emissions span a frequency range from below 10 kHz to approximately 1,000 kHz, with spectral flux densities ranging between 10−24 and 10−

Rotating Finger‐Like Structures of Jovian Magnetodisc

Geophysical Research Letters, Volume 52, Issue 15, 16 August 2025.
Abstract At Jupiter, the plasma is concentrated near the centrifugal equator, forming a magnetodisc. The planet's dipole tilt induces periodic disc flapping, generating magnetic oscillations observed by spacecraft. While centrifugal forces are theorized to drive interchange instability in this system, direct detection of such structures remains ...

Jupiter’s Metastable Companions

The Astrophysical Journal Letters
Jovian co-orbitals share Jupiter’s orbit and exhibit 1:1 mean-motion resonance with the planet. This includes >10,000 so-called Trojan asteroids surrounding the leading (L4) and trailing (L5) Lagrange points, viewed as stable groups dating back to planet

Calibration of Electrically Short Antennas Using the l = 2 Spherical Harmonic Expansion Coefficients of the Radio Brightness Distribution on the Sky Between 0.5 and 6.8 MHz

Radio Science, Volume 60, Issue 8, August 2025.
Abstract A space‐borne radio‐frequency antenna is typically located in the vicinity of a conductive spacecraft body that influences its beam. Also, at wavelengths that greatly exceed the sizes of such an antenna and spacecraft, the antenna is expected to have the beam of an equivalent short dipole.

Analysis, Testing, and Design of a UHF and HF Peer‐to‐Peer Communication System for the Europan Cryosphere

Earth and Space Science, Volume 12, Issue 8, August 2025.
Abstract This study presents a validated design of a dual‐band wireless relay system of “pucks” for through‐ice communication between a cryobot and a surface lander during a future exploration of the Europan cryosphere. The design of a terrestrial demonstration system and the results of a 103 m through‐ice system test in a relevant environment near ...

Jovian High‐Latitude Ionospheric Ions: Juno In Situ Observations

Geophysical Research Letters, 2019
The low‐altitude, high‐velocity trajectory of the Juno spacecraft enables the Jovian Auroral Distributions Experiment to make the first in situ observations of the high‐latitude ionospheric plasma. Ions are observed to energies below 1 eV.
