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

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

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
TLDR
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
