摘要

对元素的宇宙合成、恒星的演化和爆炸、早期宇宙的性质以及核天体物理学中的其他重要课题的研究处于核科学的前沿。这些研究正在推动实验室测量和理论计算,在大量投资之后,正在推动可能的边界。然而,最新的核研究成果必须经过特别准备,才能用于增进我们对宇宙的认识。这种处理需要一套核天体物理学特有的资源,并且已经为该领域开发了令人印象深刻的核反应和核结构数据集、处理代码、热核反应速率库和模拟代码和服务。然而,这些努力面临着一些严重的挑战,这些挑战在未来只会恶化,因此必须现在制定战略并采取行动,以确保这项工作的可持续未来。在详细介绍了核天体物理学所需的具体数据类型和可用的数据资源之后,讨论了这项工作中的主要挑战及其影响。为了应对这些挑战,提出了一系列倡议,并提出了实施方案和可能的方法,这些措施可能会促进我们对宇宙的理解,并加强核天体物理学领域。

Nuclear data resources and initiatives for nuclear astrophysics
Research into the cosmic synthesis of the elements, the evolution and explosion of stars, the nature of the early Universe, and other important topics in nuclear astrophysics are at the forefront of nuclear science. These studies are motivating laboratory measurements and theoretical calculations that, after significant investments, are pushing the boundaries of what is possible. The latest nuclear results, however, must be specially prepared before they can be used to advance our knowledge of the cosmos. This processing requires a set of resources unique to nuclear astrophysics, and an impressive collection of nuclear reaction and nuclear structure datasets, processing codes, thermonuclear reaction rate libraries, and simulation codes and services have been developed for the field. There are, however, some serious challenges to these efforts that will only worsen in the future, making it important to develop strategies and act now to ensure a sustainable future for this work. After detailing the specific data types needed for nuclear astrophysics and the available data resources, the major challenges in this work and their implications are discussed. A set of initiatives are proposed to meet those challenges along with suggested implementations and possible ways that they may advance our understanding of the Universe and strengthen the field of nuclear astrophysics.
