Scientific paper

We propose to measure proper motions and brightness changes for compact features in Kepler's supernova remnant over a four-year baseline. The dynamical state of Kepler's supernova remnant is poorly understood. Its multiple thermal and relativistic interacting plasmas have distinct kinematics, including a factor of two velocity disparity for the cospatial X-ray and radio bright rings. The line and continuum X-ray components are spatially separated and may also have distinct kinematics. Only with a clear dynamical picture of the remnant can we study the very basic physical issues, such as the interaction of the blast wave with circumstellar wind material, and the partition of explosion energy into bulk motions, heating, and energization of the relativistic plasma.
