摘要:

超新星爆发的核合成产率取决于多种效应:祖先演化、爆炸过程、核网络的细节和核速率。特别是在综合恒星产额的研究中,简化减少了这些不确定性。但自然界要复杂得多,要真正研究核速率,我们必须了解核合成所涉及的完整、复杂的过程。在这里,我们将讨论其中的一些复杂性,并详细介绍NuGrid合作将如何解决这些问题。

英文摘要:

The nucleosynthetic yield from a supernova explosion depends upon a variety of effects: progenitor evolution, explosion process, details of the nuclear network, and nuclear rates. Especially in studies of integrated stellar yields, simplifications reduce these uncertainties. But nature is much more complex, and to actually study nuclear rates, we will have to understand the full, complex set of processes involved in nucleosynthesis. Here we discuss a few of these complexities and detail how the NuGrid collaboration will address them.
