Solar Flare Particle-in-Cell Simulation Results — •Gisela Baumann1,2, Aake Nordlund1, Klaus Galsgaard1, Troels Haugboelle1, and Jacob Trier Frederiksen11Niels Bohr Institute, Copenhagen — 2Ruhr-Universität Bochum

Solar flares are highly energetic phenomena on the Sun, releasing huge amounts of energy, carried amongst others by particles which are accelerated up to a few hundred km/s. In this talk the first results from a flare particle-in-cell (PIC) simulation, conducted to study the particle acceleration mechanism in solar flares, are presented. Two cases are compared: with and without collisions (Coulomb scattering) and likewise for gravity.
