Abstract: |
Particle-in-cell (PIC) simulation for space plasma physics that is used in the article 'Collisionless Magnetic Reconnection in an Asymmetric Oxygen Density Configuration'. Magnetic reconnection is one of the most important energy release and transport processes in plasmas. In case of the Earth's magnetosphere, magnetic reconnection is the primary mechanism responsible for the transport of energy, mass, momentum, and magnetic flux into Earth's magnetic cavity. On the night side, magnetic flux is transported from two inflow regions (north and south) to meet in what is known as the current layer. We simulate a specific scenario where heavy particles, here oxygen, which are asymmetrically distributed accompany the flow of the more abundant plasma species (e.g. protons and electrons) towards the current layer. This simulation is designed to mimic magnetotail reconnection for an asymmetric oxygen density configuration. Oxygen is uniformly distributed above 2.5 proton inertial lengths over the current layer. |
|
Combined with the magnetic field, the distribution of charged particles in the inflow region is expected to control the rate of magnetic reconnection. This paper investigates how the reconnection process is altered by a cold, asymmetrically distributed, oxygen population, which is initially located away from the current layer in the inflow regions. A Particle-In-Cell (PIC) simulation is used to gain further insight into the dynamics of the system. The time evolution of the reconnection process proceeds rapidly compared to the cyclotron period of O^+. It, therefore, remains, to a good approximation, demagnetized. Therefore, Alfvén scaling is not an adequate description of the reconnection rate. A scaling relation for the reconnection rate for an asymmetrically distributed, demagnetized species has been developed. Additionally, we find that an asymmetric density configuration leads to a distinct motion of the reconnection site and generates an asymmetry of the diffusion region and the Hall electric field. |
