Modeling solar loop-top electron transport using stochastic methods

Department of Mathematics, University of Waikato

2012-05-18

G.1.15

Abstract:
The diffusive transport of energetic, non-relativistic electrons in a hydrogenic plasma is described by the Fokker-Planck equation. Extracting information about the system from the Fokker-Planck equation can be difficult.

In this talk I outline the advantages of expressing the Fokker-Planck equation as a system of stochastic equations. I derive moment equations using stochastic methods and compare them to simulations. I discuss what the results mean for hard X-ray emission from solar loop- top sources and explore the validity of taking a diffusion approximation.
