The nucleosynthesis of the elements between carbon and phosphorus

Nucleosynthesis of the elements between 12<=A<=31 in several astrophysical processes has been simulated using a numerical method different from those hitherto employed. The resulting compositions have been compared with astronomical abundances and with the results of previous investigations. The processes themselves have been studied in some detail, and the most important factors affecting the nucleosynthesis have been determined. (author)
