摘要

r过程核合成(在爆炸性天体物理事件中)是宇宙中观测到的大约一半重元素的来源。然而,由于核质量模型或初始条件(如种子核)的差异,文献中的r过程输出难以复制,并且在不同的研究中存在差异。我们将回顾r-过程核合成的SiRoP代码,它现在包括一个允许各种初始条件的α捕获模块和一个核灵敏度模块,以测试核质量的变化如何影响r-过程丰度模式。此外,我们将研究不同的灵敏度指标如何影响这种行为。

Alpha process nucleosynthesis and sensitivity analysis in SiRoP
The r-process nucleosynthesis (in explosive astrophysical events) is responsible for about half of the heavy elements observed in the universe. However, r-process outputs in the literature are difficult to replicate and vary across studies due to differences in nuclear mass models or initial conditions (e.g., seed nuclei). We will review the SiRoP code for r-process nucleosynthesis, which now includes an alpha-capture module that allows for a variety of initial conditions and a nuclear sensitivity module to test how changes in nuclear masses affect r-process abundance patterns. Additionally, we will examine how different sensitivity metrics influence this behavior.
