The Effects of Langmuir Wave Evolution on Type III Radio Emission

High energy electron beams are produced during solar flares and propagate through the inhomogeneous plasma of the solar corona, generating high levels of Langmuir waves which can produce Type III radio bursts. We consider the effects of long length-scale density fluctuations on these Langmuir waves using a diffusive approximation, and calculate the diffusion coefficients. We use 1-D simulations to follow the time-evolution of the Langmuir waves, and the subsequent effects on the electron beam. In addition, we simulate the Type III radio emission from the Langmuir waves, and consider the modification of brightness and spectrum due to inhomogeneities.
