The electron structures in Titan’s induced1magnetosphere observed during the T36 flyby

The interaction of Titan's ionosphere with Saturn's magnetosphere results in a complex region of perturbed magnetic fields, energetic and thermalized electrons and ions-induced magnetosphere (IM). Although the complexity of IM has been mentioned before, the local structure hasn't been investigated widely in the past years. In this case study we examine the origin of periodic electron plasma structures in Titan's induced magnetosphere observed during the T36 flyby. We use data from the electron and ion spectrometers CAPS/ELS and IMS, the Langmuir probe and electric antenna RPWS/LP, and the fluxgate magnetometer FGM to analyze plasma parameters, e.g. density and temperature, magnetic field fluctuations. The observed electron structures are periodic on a scale of ~ 20 seconds and possess signatures of acceleration from a few eV up to 700 eV. At the same time, the burst of low-frequency (around the ion-cyclotron and lower-hybrid frequency) and low-amplitude (~ 1 nT ) waves is observed. We propose that the observed electron structures are the result of a large-scale MHD instability as well as could possibly be a generic feature of Titan's induced magnetosphere structure.
