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.

Time‐variable magnetospheric radio emissions from Jupiter

Journal of Geophysical Research, 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

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.

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.

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 ...

The Shadow of a Pulsar and the Inward Radio Emission in Pulsar Magnetosphere

Chinese Journal of Astronomy and Astrophysics, 2006
We discuss observational facts that can be interpreted in terms of inward emission in pulsar magnetosphere. These include the main-pulse/interpulse anticorrelation in B1822-09 and the locations of emission and absorption features in the pulse profile of B0950+08. Weaknesses of geometrical models employing the inward emission are carefully discussed.

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.

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.
