Monday 21 Mar 20163D Propagation of Solar Energetic Particles (GAFD Seminar)

Dr Silvia Dalla - University of Central Lancashire

H103 14:30-16:00

Solar Energetic Particles (SEPs) are ions and electrons accelerated during flares and coronal mass ejections at the Sun. They can escape from the corona into interplanetary space and may reach near-Earth locations, where they pose a significant radiation risk to humans in space and satellite hardware. This talk will review our understanding of the origin and transport of SEPs, based on a large body of data gathered by spacecraft detectors and on theoretical models. It will focus on recent results of test particle simulations, which show that accurate modelling of SEP propagation requires a 3D approach, due to significant guiding centre drifts.
