Scientific paper
This paper will present the latest results of high resolution 3-D hybrid particle code simulations of Titan. The research is focused on understanding the interaction of Titan's ionosphere with Saturn's magnetosphere and the the subsequent ionospheric losses that occur. We test what role neutral winds and massive negative ions may play in that interaction. This presentation will address our current research into the Titan's plasma interaction and its effects on Titan's ionosphere. The hybrid particle code HALFSHEL contains a variety of physical and chemical models which will also be discussed. These include a chemistry package that produces the ionosphere on grid resolution of 50 km altitude, as well as the Hall and Pedersen conductivities associated with plasma neutral collisions. The specific simulations to be presented self-consistently evolve the motion of the magnetospheric O+ and several generic ionospheric species.
