Visualizing the Evolution of the Electron Fraction of a 23-Solar-Mass Star

The evolution of the explosion of a 23-solar-mass star, with a focus on the electron fraction of the ejecta.  
Electron fraction correlates with nucleosynthesis and core-collapse explosions are driven through the expansion of turbulent bubbles.  As seen here, two bubbles roughly along an axis drive the debris outward.  The contrast in the colors at the poles and equator reflects the variation in the explosive production of the elements, with radioactive Ni-56 (blue cast, the precursor to stable Fe-56) produced and ejected predominantly in the driving bubbles.
