Numerical Simulations of iCMEs and Comparison with Heliospheric Images

Abstract

CONCLUSION: Simulations are an important tool in support of HI observations * For complex events (CME-CME interaction): What happened? Testing different physical mechanisms * To test and validate methods: Simulations are like a controlled laboratory environment: CME speed and direction are known, Can vary only one parameter. We tested the Fixed-Phi and Point-P approximations. We devised a new approximation which fits better our simulated CME and is important at large elongation angles (beyond 40-deg). Lack of fast/wide CMEs may explain why fitting method work so well so far.
