Modeling the CME Ejecta and Coronal Wave of the 2012-06-14 Event Using STEREO and SOHO Observations

Coronal mass ejections (CMEs) play a crucial role in disrupting the space environment as they plow through the heliosphere after being expelled from the Sun. In particular, energetic CMEs in the corona consist of at least two elements: the classic CME ejecta or driver visible as a discrete, bright blob of erupting coronal material; and an enveloping compressive wave that forms deep in the corona due to the sudden plasma motion associated with the erupting ejecta. Using STEREO/COR2 and SOHO/LASCO coronagraph observations, we separately characterize the ejecta and surrounding coronal wave for the CME observed on 2012-06-14. These results are subsequently cast into a new form of input conditions for an Enlil MHD simulation. We discuss the model results obtained from the coronagraph observations, as well as the Enlil simulation of this event.
