In this study, we have identified the signature of a plume at Europa using magnetic field data from the Galileo E26 flyby. This result suggests the presence of persistent plume activity at Europa during the Galileo era.

This study uses an energetic ion test particle model to understand the effect that electromagnetic perturbations generated by Callisto’s thermal plasma environment has on energetic ion dynamics near the moon and accessibility of these ions to the moon. We find that over the course of a single synodic rotation of Callisto, the moon’s highly variable plasma environment has a significant on accessibility of Callisto to the energetic ion population.

In this study, we provide a detailed forecast of the magnetic field signatures that will be observable during all 12 planned Callisto flybys of the JUICE mission. We demonstrate that a large subset of the currently planned flybys will not be suitable to unambiguously disentangle Callisto’s inductive signature from plasma effects.

This study applies the AIKEF hybrid simulation model to investigate Mercury’s magnetospheric response to an impinging Coronal Mass Ejection (CME). Using AIKEF and data from the MESSENGER spacecraft, we show that parameters that characterize the CME vary on timescales much smaller than Mercury’s interaction.

This study uses the AIKEF hybrid simulation model to investigate Pluto’s interaction with the solar wind during the New Horizons flyby of Pluto.We show that the large gyroradii of ions near Pluto generate non-negligible asymmetries in Pluto’s plasma and magnetic environment, and any modeling attempts must consider these asymmetric features.

This study focused on the final four flybys of Callisto during the Galileo Mission. By using the AIKEF hybrid simulation model, we determined that no signatures of Callisto’s subsurface ocean were detected in magnetometer data during the C21, C22, C23, and C30 flybys. This study also constrained the geometry of future flybys of Callisto that aim to detect the moon’s inductive response in magnetic field data.

This study used the AIKEF hybrid simulation model to investigate magnetometer and plasma data from the Galileo C10 flyby of Callisto. In modeling Callisto’s plasma interaction with an ionosphere and induced dipole, this study identified a region in Callisto’s geometric plasma shadow directly downstream of the moon where Callisto’s inductive response was unobscured by Callisto’s plasma interaction with the Jovian magnetosphere.

This study investigated the interaction of Callisto with Jupiter’s magnetospheric plasma for differing properties of Callisto’s atmosphere and ionosphere using the hybrid simulation model AIKEF. Key scenarios that were investigated included varying the angle of incoming solar radiation with respect to the impinging magnetospheric plasma, as well as simulations where Callisto’s distance to the center of Jupiter’s magnetospheric current sheet was changed.

This study used the AIKEF hybrid simulation model to investigate three Cassini flybys of the Saturnian moon Titan. By comparing model output to magnetic field and plasma data, the study found that observations of a “split tail” of heavy ions downstream of Titan is an omnipresent feature of Titan’s plasma interaction with the Saturnian magnetosphere.
