Anisotropic Jovian electron transport

Abstract

Jovian electrons are released into the heliosphere as a result of events caused by the dynamics within the Jovian magnetosphere, including magnetic flux tubes formed in the magnetosphere because of centrifugal forces as a result of the fast rotation rate of Jupiter. A two-dimensional focused transport model is used to simulate the propagation of Jovian electrons in the heliosphere. The optimization of the model for parallel computing was investigated as it increases the performance as well as determines the optimal runtime of the model. Observed intensities of Jovian electrons from the PSP spacecraft is used to yield the best-fitting mean free paths when compared to simulation results from the twodimensionally focused transport model. The obtained mean free path values are compared to various mean free paths from different sources as well as to the theoretical estimates. These mean free paths are used in the model to simulate two types of Jovian events: The Jovian clock that releases Jovian electrons, in 10-hour and 5-hour periodicities and Jovian jets where Jovian electrons are released sporadically.
