Coronal Mass Ejection Reconstruction from Three Viewpoints via Simulation Morphing. I. Theory and Examples

摘要: The problem of reconstructing the three-dimensional (3D) density distribution a coronal mass ejection (CME) from three simultaneous coronagraph observations is timely in that COR1 and COR2 coronagraphs on dual-spacecraft STEREO mission complement LASCO SOHO satellite Mk4 Mauna Loa. While separation angle between spacecraft Earth depends time since launch 2006, reconstruction always severely underinformed. So far, all 3D efforts have made use relatively simple parameterized models order to determine structure CME. Such approaches do not utilize power MHD simulation inform reconstruction. This paper considers situation which specific CME event observed viewpoints later simulated by solving equations. then subjected an invertible morphological operator chosen so morphed most consistent with three-viewpoint data. operations are explained mathematically synthetic examples given. practical application CMEs data discussed.
