论文摘要
尽管对中子星合并事件GW170817的多通函检测证实，通过快速中子捕获过程（$ r $ - 过程），合并正在产生大自然的重型元素，这是与Translead核的产生有关的许多问题 - actacinides-actacinides-仍然需要答复。在这篇简短的评论论文中，我们总结了$ r $ process的actinide生产的一般要求以及核物理学投入的影响。我们还讨论了从不同角度来解决中子星融合中的actinide生产的最新努力，包括未来的Kilonova可能探索的签名和$γ$ -Ray观测，金属贫困恒星中的丰度散射以及在Solar System中的短期放射性actactive所构成的约束。
Although the multimessenger detection of the neutron star merger event GW170817 confirmed that mergers are promising sites producing the majority of nature's heavy elements via the rapid neutron-capture process ($r$-process), a number of issues related to the production of translead nuclei -- the actinides -- remain to be answered. In this short review paper, we summarize the general requirements for actinide production in $r$-process and the impact of nuclear physics inputs. We also discuss recent efforts addressing the actinide production in neutron star mergers from different perspectives, including signatures that may be probed by future kilonova and $γ$-ray observations, the abundance scattering in metal-poor stars, and constraints put by the presence of short-lived radioactive actinides in the Solar system.
