Abstract
Solar wind charge exchange (SWCX) generated soft X-rays are used
extensively to study the interfaces between charged and neutral
particles throughout the solar system. This paper outlines the
development of a model of Jupiter’s magnetosheath using MHD derived
boundary equations and a combination of in situ Juno measurements and
numerical models for neutral and charged particle distributions. These
are then used to model SWCX emissions in the Jovian magnetosheath for
the O$_{VII}$ triplet to determine if the magnetosheath could be
imaged in a similar fashion to the planned SMILE mission at Earth. We
determine that whole detector counts per minute range from
10$^{-5\pm1}$ to 10$^{-3\pm1}$
for various spacecraft, and, as such, argue that with current instrument
sensitivity it is infeasible to study the X-ray emissions from the
Jovian magnetosheath. However, with a theoretical x-ray imager with an
effective area of 1m$^2$ and FOV of
$120^{\circ}\times120^{\circ}$
increases to a peak of
$\sim$10$^{0\pm1}$ c/min when
observing from a distance of 40 R$_J$. We also discuss the
implications of the low emission rates on other higher signal X-ray
observations at Jupiter and the possibility of Saturn being a better
target for such a mission.
