Weaver, T A; Woosley, S E

An attempt is reported to build self-consistent evolutionary models of complete massive stars, starting from their observable zero-age main sequence configurations, and evolving through their various hydrostatic nuclear burning stages, iron core collapse, bounce, outward-going shock formation, and finally, explosive nucleosynthesis and supernovae light curve formation. The model incorporates implicit hydrodynamics with a new treatment of time-dependent convection and semiconvection, and a careful treatment of the complexities of the advanced stages of stellar burning. The model was used to completely evolve population I stars of 15 and 25 M/sub solar mass/, with excellent agreement with the known properties and the prediction of other properties. 65 references.
