论文摘要

得益于核和天体物理学之间的长期合作,我们对恒星核合成有很好的了解,除了TI和一些中子捕获元素周围的元素。从观测和银河化学演化模型之间的比较,尽管爆炸机制尚不清楚,但有必要具有与核心溢流超新星相关的快速中子捕获过程。本文还显示了旋转巨星的影响。许多关键要素可以在紫外线中独家获得,因此,如果没有紫外线光谱,就无法完全理解宇宙中元素的起源。

Thanks to the long-term collaborations between nuclear and astrophysics, we have good understanding on stellar nucleosynthesis, except for the elements around Ti and some neutron-capture elements. From the comparison between observations and Galactic chemical evolution models, it is necessary to have the rapid neutron-capture process associated with core-collapse supernovae, although the explosion mechanism is unknown. The impact of rotating massive stars is also shown in this paper. Many of the key elements can be exclusively obtained in the UV, and therefore without UV spectra it would not be possible to fully understand the origin of elements in the universe.
