Resumen:
We present new results of Cassini's T9 flyby. These results are
based on Cassini Plasma Spectrometer (CAPS) and Cassini Magnetometer
(MAG) measurements with new ion and electron fluid parameter results
presented. Compositional evidence shows a proton only interaction with
Titan which changes the nature of the interaction substantially with
significantly lower external pressures than that for TA where heavy ions
dominated the magnetospheric plasma. Within Titan's induced magnetotail,
referred to as event 1, we observe ionospheric field aligned outflows
with flux ~ 8x106 ions/cm2/s and speed ~ 8 km/s. For event 2 we observe
H+ and H2 + ions also moving away from Titan and field aligned with
total flux ~ 3x106 ions/cm2/s and speeds ~ 30 km/s. Event 2 is probably
draped field lines with scavenging of H2 + pickup ions formed inside the
induced magnetosphere boundary of the interaction.
