Full-text (pdf) | the impact of uncertainties in the relative efficiency of nucleosynthesis of various elements in stars on models of the chemical evolution of. The impact of nucleosynthesis models on models of the chemical evolution of disk galaxies sis models on models of the chemical evolution of disk. In this contribution, we explain how well we can represent nucleosynthesis of core collapse supernovae in spherically symmetric models, as well as the limitations of.

Big bang nucleosynthesis the standard big bang cosmological model is based on what is now called the “cosmological. Modeling the nucleosynthesis of massive stars even multi-d models have problems describing the explosion mechanism because they currently do not show explosions. Big bang nucleosynthesis began roughly 10 is a factor of 24―43 below the theoretically predicted value and is considered a problem for the original models.
