Abstract—

It is believed that microscopic life is possible in the subglacial ocean of Europa, a satellite of Jupiter. However, Jupiter’s radiation belts make it difficult to detect it on the surface or at shallow depths. Using numerical simulations, we investigated the influence of the inclination of the magnetic dipole of Jupiter, the Alfvén wings, and the induced field of Europa on the dynamics of electrons near the satellite of Jupiter, which made it possible to refine the map of radiation doses on Europa’s surface, obtained earlier in the approximation of the guiding center.
