Dynamic Mapping of Solar Eruptions
Abstract
We present the results of a prominence mapping effort designed to extract the dynamics of erupting prominences and CMEs. The material from partially erupting prominences can fall back to the sun, tracing out the topology of the mid- and post-eruptive corona. One question involving the range of observed behavior is the role of magnetic field topology and evolution in determining the motion of the erupting prominence material. A variable-g ballistic approximation is applied to study the motion of the material, using the deviations from constant angular momentum as a means of quantifying the local Lorentz (and other) forces on each piece of material. Variations in dynamic behavior can be traced back to changes in the local magnetic field. We discuss the use of the prominence trajectories as a means of diagnosing eruptive topologies.
