Kippenhahn Diagrams as a function of the C12(a,g) rate

The movie shows the evolution of the helium core till from end of central helium burning till core collapse. Convection is shown as green hatching, semiconvection as red cross hatching. Specific energy generation (blue) and energy losses (pink; mostly by plasma neutrinos), are shown as color shading and each "level" of higher color intensity represents an order of magnitude higher value, in erg per gram and second, starting at 1/10 erg per gram and second.

On request, arbitrary amounts of data can be supplied.
