The first observations of Jupiter made by the Chandra X-Ray Observatory revealed a powerful x-ray aurora located in the polar caps. The x-ray emission exhibited a forty minute periodicity. Such 40-minute periodicities have previously been seen in energetic particle fluxes and in Jovian radio emission. This paper presents scenarios in which the x-ray emission is produced by energetic heavy ion precipitation, either on open field lines connecting to the solar wind or on closed field lines reaching to the outer magnetosphere. Both scenarios require the existence of field-aligned electric fields at a radial distance of a few Jovian radii. The potential needed to produce the observed x-rays is either about 200 kV (solar wind case) or in excess of 10 MV (magnetospheric case). The estimated field-aligned currents are in the 10 to 1000 MA range depending on the scenario. Other implications of the observed auroral x-ray emission will also be discussed.
