Analyzing CME Substructure and Chirality from Synthetic Polarization Observations
Abstract
Recent work (Deforest et al., 2017) has demonstrated the power of white-light polarization for pinpointing the 3D location of CME substructure and characterizing its chirality using coronagraph observations. In this paper, we further explore the capability of this technique by creating synthetic white-light observations from a simulation of an erupting CME containing realistic substructure. We extract information about the CME chirality from the synthetic polarization, and compare to the "ground truth" of the simulation. We analyze how CME orientation relative to the viewer affects our results, and consider the implications of this type of analysis for studying how CME substructure evolves in the young solar wind.
