Supernova nucleosynthesis had been studied in 1-dimensional and multi-dimensional numerical simulations. I briefly summarize the supernova nucleosynthesis with results of the 1-dimensional simulations because essences of supernova nucleosynthesis are kept and easily understood. Products of supernova nucleosynthesis have clues to constrain origin of metal-poor stars and supernova explosion...

Even in nucleosynthesis processes involving nuclei at or close to stability, not all reaction rates are experimentally constrained. In addition, even with the presence of measurements, these are often not able to fully constrain the stellar reaction rate due to thermal population of excited target states in the stellar plasma or bear large error bars. From a theory point of view, certain...

A nuclear reaction flow, appropriately scaled, gives the number of nuclei of a particular species undergoing a particular reaction per unit time. Such information provides important clues as to how nuclei are synthesized in an astrophysical environment and which nuclear reactions govern the resulting yields. For example, reaction flows in the s process of nucleosynthesis show the main...

Unraveling the core-collapse supernova (CCSN) mechanism is problem that remains essentially unsolved despite more than four decades of effort. Spherically symmetric models with high physical fidelity generally fail to produce explosions, and it is widely accepted that CCSNe are inherently multi-dimensional. Progress in realistic modeling has occurred recently through the availability of...
