Unusually strong magnetic fields in Titan's ionosphere: T42 case study

Coates, A. J.; Russell, C. T.; Wei, H. Y. +7 more

Observations of unusually large magnetic fields in the ionosphere indicate periods of maximum stress on Titan's ionosphere and potentially of the strongest loss rates of ionospheric plasma. During Titan flyby T42, the observed magnetic field attained a maximum value of 37 nT between an altitude of 1200 and 1600 km, about 20 nT stronger than on any…

Background and pickup ion velocity distribution dynamics in Titan's plasma environment: 3D hybrid simulation and comparison with CAPS T9 observations

Hartle, R. E.; Sittler, E. C.; Cooper, J. F. +2 more

In this report we discuss the ion velocity distribution dynamics from the 3D hybrid simulation. In our model the background, pickup, and ionospheric ions are considered as a particles, whereas the electrons are described as a fluid. Inhomogeneous photoionization, electron-impact ionization and charge exchange are included in our model. We also tak…
