MHD Simulations of CME with Associated Prominence Eruption

We present an overview of magnetohydrodynamic (MHD) simulations of prominence-forming coronal flux ropes and the development of coronal mass ejection (CME) with associated prominence eruption. The simulations found the formation of a prominence–cavity system that qualitatively reproduces several observed features including the cavity, the prominence “horns”, and the central “cavity” enclosed in the “horns” above the prominence. We discuss the magnetic structure corresponding to these observed features and the effect of the prominence weight on the stability and eruption of the flux rope.
