Are Saturn’s Interchange Injections Organized by Rotational Longitude?

Published in Journal of Geophysical Research: Space Physics, 2019

When estimating the rotation rate of Jupiter and Saturn scientists often use a periodic signal of radio emission…we analyze interchange's occurrence rate, as observed in particle data from the Cassini spacecraft, with respect to two longitude systems…We find that interchange occurrence shows only weak organization in these longitude systems as compared to organization by local time.

Statistical study of the energetic proton environment at Titan’s orbit from the Cassini spacecraft

Published in Journal of Geophysical Research: Space Physics, 2018

A statistical study of the energetic proton environment at Titan's orbit as captured by the MIMI/LEMMS and MIMI/CHEMS instruments is performed…ion fluxes reveals a weak asymmetry in Saturn local time with the highest fluxes occurring in the premidnight sector of the magnetosphere…This model can be used to better understand the interaction of Titan with the magnetosphere and the energy deposition by energetic particles below the main ionospheric peak.

Interchange Injections at Saturn: Statistical Survey of Energetic H+ Sudden Flux Intensifications

Published in Journal of Geophysical Research: Space Physics, 2018

Featured article in July 2018. Studying high‐energy particles around magnetized planets is essential to understanding processes behind mass transport in planetary systems…We present a computational method to identify and rank interchange injections using high‐energy particle fluxes from the Cassini mission to Saturn. These events have never been identified computationally, and the resulting database is now publically available…
