Jupiter’s slow dayside magnetic merging and fast rotation produce an unusual magnetic topology that can explain its polar aurora. Jupiter’s bright persistent polar aurora and Earth’s dark polar region indicate that the planets’ magnetospheric topologies are very different. High-resolution global simulations show that the reconnection rate at the interface between the interplanetary and jovian magnetic fields is too slow to generate a magnetically open, Earth-like polar cap on the time scale of… Expand

Revealing the source of Jupiter’s x-ray auroral flares
Jupiter’s unique x-ray aurora is driven by the same processes as Earth’s: Heavy ion scattering by electromagnetic waves. Jupiter’s rapidly rotating, strong magnetic field provides a naturalExpand

Accelerated Flows at Jupiter's Magnetopause: Evidence for Magnetic Reconnection Along the Dawn Flank
We report on plasma and magnetic field observations from Juno's Jovian Auroral Distributions Experiment and Magnetic Field Investigation at eighteen magnetopause crossings when the spacecraft wasExpand
The Jovian auroral oval
Jupiter's aurora shows, among other features, a persistent, continuous oval of luminosity that encircles each magnetic pole and maps along magnetic field lines to the middle magnetosphere (r ≈ 30Expand
Solar wind interaction with Jupiter's magnetosphere
[1] We present a review of observations and theories of the dynamics of Jupiter's magnetosphere from Pioneer to New Horizons. We suggest that Jupiter's solar wind–driven magnetospheric flows are dueExpand
Improved mapping of Jupiter's auroral features to magnetospheric sources
[1] The magnetospheric mapping of Jupiter's polar auroral emissions is highly uncertain because global Jovian field models are known to be inaccurate beyond ∼30 RJ. Furthermore, the boundary betweenExpand
Juno observations of large-scale compressions of Jupiter's dawnside magnetopause
We investigate the structure of Jupiter's dawnside magnetopause using observations obtained by particle and fields instrumentation on the Juno spacecraft. Characterization of Jupiter's magnetopauseExpand
Energetic particle signatures of magnetic field‐aligned potentials over Jupiter's polar regions
Recent results of the first ever orbit through Jupiter's auroral region by NASA's Juno spacecraft did not show evidence of coherent acceleration in the auroral or polar region. However, in thisExpand
Ionospheric control of magnetotail reconnection
It is shown that the electrodynamic interaction between Earth’s magnetosphere and ionosphere produces an asymmetry consistent with observed distributions in nightside reconnection and plasmasheet flows and in accompanying ionospheric convection. Expand
Implications of rapid planetary rotation for the Dungey magnetotail of Saturn
[1] Employing our current understanding of the structure and dynamics of Saturn's magnetosphere, we present a time-dependent model of the kronian Dungey cycle magnetotail, which is based upon aExpand
A global magnetohydrodynamic simulation of the Jovian magnetosphere
We have developed a three-dimensional global magnetohydrodynamic simulation of the interaction between the solar wind and a rapidly rotating magnetosphere and applied it to Jupiter. For fixed solarExpand
Quasi‐periodic polar flares at Jupiter: A signature of pulsed dayside reconnections?
[1] The most dynamic part of the Jovian UV aurora is located inside the main auroral oval. This region is known to regularly show localized but dramatic enhancements on timescales of several tens ofExpand
