Magnetosphere-ionosphere coupling in Jupiter's middle magnetosphere: Computations including a self-consistent current sheet magnetic field model

Nichols, J. D.

In this paper we consider the effect of a self-consistently computed magnetodisc field structure on the magnetosphere-ionosphere coupling current system at Jupiter. We find that the azimuthal current intensity, and thus the stretching of the magnetic field lines, is dependent on the magnetosphere-ionosphere coupling current system parameters, i.e.…

Nightside reconnection at Jupiter: Auroral and magnetic field observations from 26 July 1998

Bonfond, B.; Vogt, M. F.; Grodent, D. +3 more

In this study we present ultraviolet and infrared auroral data from 26 July 1998, and we show the presence of transient auroral polar spots observed throughout the postdusk to predawn local time sector. The polar dawn spots, which are transient polar features observed in the dawn sector poleward of the main emission, were previously associated wit…

Modeling of Jupiter's auroral curtain and upper atmospheric thermal structure

Clarke, J. T.; Cohen, I. J.

A three-dimensional simulation that takes into account the altitude extent of auroral emission along the line of sight has been applied to the analysis of auroral images of Jupiter taken by the Hubble Space Telescope (HST). The simulation's input auroral emission profile with altitude was expanded by an emission scale height factor ranging from n …
