Cassini observations of narrowband radio emissions in Saturn's magnetosphere [PDF]
Journal of Geophysical Research: Space Physics, 2010 The Radio and Plasma Wave Science instrument (RPWS) on board the Cassini spacecraft has detected numerous narrowband radio emissions in Saturn's magnetosphere from September 2005 to May 2007. Typically, the narrowband radio emissions occur after an intensification of Saturn kilometric radiation (SKR) and last for several days.

Detecting Magnetospheric Radio Emission from Giant Exoplanets
The Astrophysical Journal, 2022 Abstract As radio astronomy enters a golden age, ground-based observatories are reaching sensitivities capable of unlocking a new and exciting field of exoplanet observation. Radio observation of planetary auroral emission provides unique and complementary insight into planetary science not available via orthodox exoplanet observation ...

A mechanism for bursty radio emission in planetary magnetospheres
Geophysical Research Letters, 1990 Bursty radio emissions are often observed from the polar magnetospheres of the Earth, Jupiter, Saturn, and Uranus in addition to the smooth radio emissions commonly detected. We show that in plasma regimes in which the electron plasma frequency is less than the electron cyclotron frequency, anisotropic electron beams or gyrating electron beams can ...

Constraints on magnetospheric radio emission from Y dwarfs [PDF]
Monthly Notices of the Royal Astronomical Society, 2019 Abstract As a pilot study of magnetism in Y dwarfs, we have observed the three known infrared variable Y dwarfs WISE J085510.83−071442.5, WISE J140518.40+553421.4, and WISEP J173835.53+273258.9 with the NSF’s Karl G. Jansky Very Large Array in the 4–8 GHz frequency range.

The Response of Broadband Kilometric Radiation to Compressions of the Jovian Magnetosphere
The Astrophysical JournalIn the planetary magnetosphere, plasma waves act as the medium for particles to transfer energy. Jupiter is the largest planet in our solar system, and the giant magnetosphere is full of energetic particles, producing intense radio emissions.

High-latitude propagation studies using a meridional chain of LF/MF/HF receivers [PDF]
Annales Geophysicae, 2004 For over a decade, Dartmouth College has operated programmable radio receivers at multiple high-latitude sites covering the frequency range 100-5000kHz with about a 1-s resolution. Besides detecting radio emissions of auroral origin, these receivers

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.Abstract Saturn's ring current, which modulates the global magnetic field configuration, varies dynamically with hot plasma injections. However, quantifying transient magnetic field disturbances remains challenging in the absence of in situ measurements on Saturn's surface.

Cyclotron absorption of radio emission within pulsar magnetospheres [PDF]
Monthly Notices of the Royal Astronomical Society, 2001 ABSTRA C T Absorption of radio emission through normal cyclotron resonance within pulsar magnetospheres is considered. The optical depth for cyclotron damping is calculated using a plasma distribution with an intrinsically relativistic spread. We argue that such a broad distribution is plausible for pulsar plasmas and that it implies that a class of ...
