Abstract

Computer simulation was employed here to study the process of heating in space plasmas. In the simulation, the one-dimensional particle-in-cell simulation method was used and the Maxwell’s Equations solved using the Finite Difference Time Domain (FDTD) method. The modified one-dimensional Kyoto University electromagnetic particle code with relativistic effect consideration (MATLAB Version) was used. The simulation results obtained is a plot of energy, which shows heating at the beginning of the simulation with the system reaching its thermodynamic equilibrium later in the simulation. Other results obtained where the velocity vector space plot showing a drift maxwellian nature, indicating collisions between particles and two other Spatial Electric and Magnetic fields plots. The results in the simulation showed that the heating in the space plasmas are caused mainly by binary collisions between the particles.
