A model is developed for the nucleosynthetic yields from the supernova explosion of a massive star of the sort which has been proposed as the initiating event in the formation of the solar system by Cameron and Truran (1977). Calculations start with the Hugoniot curves, estimating the preshock conditions from a 25 solar masses model at the start of core collapse. It is shown that the products of static carbon burning dominate abundance patterns in the ejecta. Both explosive carbon burning and explosive neon burning contribute significantly to Al-26. The production of Al-26 in this model is consistent with the trigger hypothesis.
