Control of Jupiter's radio emission and aurorae by the solar wind

Gurnett, D. A.; Persoon, A. M.; Dougherty, M. K. +14 more

Radio emissions from Jupiter provided the first evidence that this giant planet has a strong magnetic field and a large magnetosphere. Jupiter also has polar aurorae, which are similar in many respects to Earth's aurorae. The radio emissions are believed to be generated along the high-latitude magnetic field lines by the same electrons that produc…

Ultra-relativistic electrons in Jupiter's radiation belts

Johnson, W. T. K.; Klein, M.; Hofstadter, M. +18 more

Ground-based observations have shown that Jupiter is a two-component source of microwave radio emission: thermal atmospheric emission and synchrotron emission from energetic electrons spiralling in Jupiter's magnetic field. Later in situ measurements confirmed the existence of Jupiter's high-energy electron-radiation belts, with evidence for elect…

The dusk flank of Jupiter's magnetosphere

Gurnett, D. A.; Dougherty, M. K.; Hospodarsky, G. B. +8 more

Limited single-spacecraft observations of Jupiter's magnetopause have been used to infer that the boundary moves inward or outward in response to variations in the dynamic pressure of the solar wind. At Earth, multiple-spacecraft observations have been implemented to understand the physics of how this motion occurs, because they can provide a snap…

Planetary science: Magnetic moments at Jupiter

Hill, Thomas W.

The coming together of two spacecraft near Jupiter provided a unique opportunity to investigate the giant planet's magnetic field -- and the results, collected in this issues, are stunning
