Beschreibung:
The general objective of this project is to advance our theoretical understanding of Io's atmosphere by studying how various atomic and molecular species are lost from this atmosphere and are distributed near the satellite and in the circumplanetary environment of Jupiter. The project is divided into well-defined studies described for the likely dominant atmospheric gases involving species of the SO2 family (SO2, SO, 02, 0, S) and for the trace atmospheric gas atomic sodium. The relative abundance of the members of the S02 family and Na (and its parent Na(x)) at the satellite exobase and their relative spatial densities beyond in the extended corona of lo are not well known but will depend upon a number of factors including the upward transport rate of gases from below, the velocity distribution and corresponding escape rate of gases at the exobase, and the operative magnetospheric/solar-photon driven chemistry for the different gases. This question of relative abundance will be studied in this project.
