Simulation on solar Type III radio bursts from magnetic reconnection region View all abstracts by submitter

Jun-ichi Sakai   Submitted: 2005-02-22 03:56

We investigate the wave emission process of solar Type III radio bursts from magnetic reconnection region in a solar flare by using two dimensional, electromagnetic, relativistic Particle-In-Cell (PIC) code. We initially impose two plasma populations, background dense plasma and hot electrons that can be generated by magnetic reconnection process in a solar flare. We investigated two cases: model (1) where the hot electron beams propagate obliquely to the magnetic field, while in model (2) the hot electron beams propagate along the magnetic field. We found that hot electron plasmas lead to the generation of Langmuir waves and the generated Langmuir waves can be converted to the electromagnetic waves (solar Type III radio bursts) through the linear direct mode conversion process. The second harmonic emission is generated with time delay and the amplitude larger than that of fundamental emission.
