Uranus as a radio source.
Abstract
The morphology of the Uranus radio emission is complex, with at least 7 distinct components, each manifesting different characteristics in the frequency and time domains. The active radio regions of the planet are located above the magnetic poles, in the magnetic equator region near the planet, and in the density cavity between the magnetopause and the dense inner magnetosphere. Analysis of the radio emissions had led to (1) an accurate measure of the internal rotation period of the planet; (2) information on local plasma conditions and on the structure of the downstream magnetopause; (3) additional evidence for a substorm-like response of the magnetosphere to the solar wind; and (4) information on dayside and nightside ionospheric electron densities. Uranus is the fourth planet known to emit low-frequency radio waves and the fifth thought to have lightning.
