[67.06] Modeling Coronal Mass Ejections

J. A. Linker, Z. Mikic, P. Riley, R. Lionello (SAIC)

Coronal mass ejections (CMEs) are immense eruptions of plasma and magnetic field that are propelled outward from the sun. CMEs are an important aspect of Space Weather at Earth, as they are believed to be the primary cause of nonrecurrent geomagnetic storms. In this talk, we compare eruptions generated by the "flux cancellation" (Linker et al., Phys. Plasmas 10, 1971, 2003) and "breakout" (Antiochos et al., ApJ 512, 985, 1999) models and discuss how these mechanisms might be distinguished by coronal and interplanetary observations.

Work supported by NASA and the Center for Integrated Space Weather Modeling (an NSF Science and Technology Center).
