论文摘要
核天体物理学是一个多学科的领域,对核数据的需求很大。在其各个领域中,恒星进化和核合成显然与核物理学最密切相关。对天体物理应用的核数据的需求挑战了实验技术以及当前核模型的鲁棒性和预测能力。尽管过去几年的进展令人印象深刻,但仍然存在重大问题和难题。在目前的贡献中,仅讨论了少数核天体物理学的特定方面。这些涉及一些实验进展,与核合成的所谓的S和P过程的关键反应有关,这是预测R-Procoress核合成感兴趣的中子富含中子中子核的理论上的努力,以及最近在核主体物理学中引入机器学习技术。
Nuclear astrophysics is a multi-disciplinary field with a huge demand for nuclear data. Among its various fields, stellar evolution and nucleosynthesis are clearly the most closely related to nuclear physics. The need for nuclear data for astrophysics applications challenges experimental techniques as well as the robustness and predictive power of present nuclear models. Despite impressive progress for the last years, major problems and puzzles remain. In the present contribution, only a few nuclear astrophysics specific aspects are discussed. These concern some experimental progress related to the measurement of key reactions of relevance for the so-called s-and p-processes of nucleosynthesis, the theoretical effort in predicting nuclear properties of exotic neutron-rich nuclei of interest for the r-process nucleosynthesis, and the recent introduction of machine learning techniques in nuclear astrophysics applications.
