We compare the magnetic breakout model for solar coronal mass ejections (CMEs) of Antiochos, DeVore, & Klimchuck [1] to coronagraph and in-situ observations. We study the effect of adaptive mesh refinement (AMR) on the density structures and coronagraph dynamics predicted by the model. Synthetic coronagraph images are shown to reproduce the dark cavity and bright rim features of 3-part CME observations. Height-time plots are generated and compared with LASCO observations. The breakout model creates a flux-rope like structure during eruption that shares many properties with interplanetary magnetic cloud observations, e.g. internal fields that can be well described by a linear, force-free cylinder. This work is supported by ONR and NASA.
