Not All Shocks Are Created Equal: Shock Acceleration During the 2013 April 11 Solar Energetic Particle Event

A new shock-capturing tool is introduced to study the coronal mass ejection-driven shock originating from the low solar corona. Multi-spacecraft observations, including SOHO, SDO, GOES, ACE near Earth, and STEREO-A/B, are used for model-data comparison and validation. We show the simulated observables, including extreme ultraviolet and white-light images, shock properties, as well as proton time-intensity profiles and energy spectra, and compare them to observations. Our simulation results demonstrate the efficient integration of the Poisson bracket scheme with a particle solver in the Space Weather Modeling Framework (SWMF) for simulating a practical SEP event, as well as the capability of capturing a time-evolving shock surface in the SWMF.
