Simulation of the impact of a plasmaspheric plume on the dayside magnetic reconnection
Abstract
During times of strong magnetic activity, cold dense plasma from the plasmasphere typically forms a plume extending towards the dayside magnetopause and eventually reaching it. In this work, we present a two-dimensional fully kinetic Particle-In-Cell simulation of magnetic reconnection hit by a propagating plasmaspheric plume. We observe three main phases: magnetic reconnection before and during the impact of the plume, and the full interaction when the plume is well engulfed in the reconnection site. We show that the composition of the plume (cold ions) does not vary the magnetic reconnection rate, which depends only on the inflowing magnetic field and total ion density, whatever the phase we are in. We finally present some opportunities offered by this unprecedented large simulation, whose aimed at being shared in the community, in term of comparison with spacecraft data and of test use for machine learning activity, this last being a main objective of the AIDA H2020 project. This work has received funding from the European Union's Horizon 2020 research and innovation programme under grant agreement No 776262 (AIDA, www.aida-space.eu).
