Our recent modeling work reconstructed the thermodynamic evolution of several plasma structures (prominence, prominence-coronal transition region, and coronal-like plasma) within the radial expansion of a coronal mass ejection (CME) by examining heliopsheric ion composition within the ejecta. This study suggested that the components experienced rapid, continuous, and non-uniform heating as they travelled away from the Sun. The work indicated that comprehensive CME studies require multi-wavelength plasma observations along with a wide off-limb field of view to capture the extent of the evolution. However, the dynamic nature of the eruption makes it difficult to capture the plasma’s temporal and spatial evolution with a single narrowband imager or high resolution spectrometer
