Numerical simulation of auroral magnetospheric radio emission

2012 37th International Conference on Infrared, Millimeter, and Terahertz Waves, 2012
Simulations have been conducted at the University of Strathclyde to study the electrodynamics of the cyclotron maser instability responsible for generating auroral magnetospheric radio emission from stars and planets with a dipole like magnetic field configuration.

Phenomenology of magnetospheric radio emissions

1983
Jupiter has now been observed over 24 octaves of the radio spectrum, from about 0.01 MHz to 300,000 MHz. Its radio emissions fill the entire spectral region where interplanetary electromagnetic propagation is possible at wavelengths longer than infrared. Three distinct types of radiation are responsible for this radio spectrum.

Numerical investigation of auroral magnetospheric radio emission

2012 Abstracts IEEE International Conference on Plasma Science, 2012
Summary form only given. In recent years, there has been considerable published research and debate on an instability produced within an electron beam transported into an increasing magnetic field. Due to conservation of energy and magnetic moment, a velocity distribution is produced having a significant pitch spread and effective population inversion ...

An interpretation of banded magnetospheric radio emissions

Journal of Geophysical Research: Space Physics, 2001
Recently published Active Magnetospheric Particle Tracer Explorers/Ion Release Module (AMPTE/IRM) banded magnetospheric emissions, commonly referred to as “(n + 1/2)fce” emissions, where fce is the electron gyrofrequency, are analyzed by treating them as analogous to sounder‐stimulated ionospheric emissions.

Chaotic Temporal Variability of Magnetospheric Radio Emissions

Space Science Reviews, 2003
Nonthermal magnetospheric radio emissions provide the radio signatures of solar-terrestrial connection and may be used for space weather forecasting. A three-wave model of auroral radio emissions at the fundamental plasma frequency was proposed by (1994) involving resonant interactions of Langmuir, whistler and Alfven waves.

Introduction : Planetary magnetospheres, ionospheres, thermospheres and radio emissions

Planetary and Space Science, 1993
Abstract The annual European Geophysical Society General Assembly covers, among others, the field of planetary environments under the form of an open session on Planetary Magnetospheres, Ionospheres and Thermospheres, complemented by a session on Planetary Radio Emissions.

Time‐variable magnetospheric radio emissions from Jupiter

Journal of Geophysical Research: Planets, 1993
Jupiter is the source of a large number of independent nonthermal radio sources, all of which vary with time. The known causes of the variations include planetary rotation modulation, modulation by Io and/or its torus, and influence by the solar wind which can reach surprisingly deep into the Jovian magnetosphere. However, a significant number of radio

Numerical simulations of bursty radio emissions from planetary magnetospheres

Journal of Geophysical Research: Space Physics, 1992
The Voyager spacecraft observed both smooth and bursty radio emissions from Uranus and Neptune. These emissions are known to be freely propagating primarily in the right‐hand circularly polarized (RCP) mode with the bursty emissions having burst periods as short as a few tenths of a second and the smooth emissions being observed over periods of a few ...

The main source of radio emission from the magnetosphere of Uranus

Journal of Geophysical Research: Space Physics, 1987
Observations of kilometric radiation from Uranus made with the planetary radio astronomy experiment on the Voyager 2 spacecraft are presented and discussed. Similarities between the auroral kilometric radiation from Earth and the observed Uranus emission are pointed out.

Observations of low‐frequency radio emissions in the Earth's magnetosphere

Journal of Geophysical Research: Space Physics, 1989
A study is made of electromagnetic radiation in the Earth's magnetosphere in the frequency range between 10 kHz and 80 kHz using data from the University of Minnesota Plasma Wave Experiment aboard the IMP 6 satellite. Two types of radio emissions are investigated.
