Title:
Analyzing the substructures of Coronal Mass Ejection using WISPR

Abstract:
Parker Solar Probe (PSP; launched in 2018) and Solar Orbiter (SoLO; launched in 2020) observe the Sun from unprecedented close-in and out-of-ecliptic orbits. This unique and high-resolution data will give us new insights about the initiation and early evolution of coronal mass ejections (CMEs) in the inner heliosphere. Especially the combination of remote sensing solar imagery in EUV and white-light together with in-situ plasma and field measurements is expected to reveal a better understanding about the nature of CMEs. The solar source region, the eruption characteristics and underlying magnetic reconnection process are expected to be reflected in the different CME substructures, e.g., showing shell-like structures and rays, which are not yet fully understood. To investigate the complexity of small-scale features belonging to coronal mass ejections (CMEs), we use high-resolution white-light image data from heliospheric imager WISPR, aboard Parker Solar Probe. We analyzed a CME case study using a multi-spacecraft approach to support the analysis and data interpretation.
