论文摘要
这是关于我在亨利·诺里斯·罗素(Henry Norris Russell)在2020年1月在我的亨利·诺里斯·罗素(Henry Norris Russell)演讲中提出的有关稀有光元素(Li),铍(BE)和Boron(B)的一些研究的一些亮点的报告。这不是这些光元素上的作品的全面综述,但在这些光元素上进行了大爆炸元素的部分。它包括有关它们如何观察到的信息,无论是历史还是当前,以及确定其丰度的困难。 %它通过银河系的历史来追溯这些元素的演变。 Li,Be和B的生产正在进行中,因此最年轻的恒星包含最多的LI,并且他们的时间更少。这三个要素在恒星内部都很容易破坏,但是对耗尽其表面含量的特定核融合反应的敏感性不同。此功能使它们非常好的探针探究了其他不可观察的恒星内饰。它还可以增强三个或三个或多个在恒星内部工作中的各个过程时的使用。
This is a report on some highlights of some research on the rare light elements, lithium (Li), beryllium (Be), and boron (B), that I presented in my Henry Norris Russell Lecture in January, 2020. It is not a comprehensive review of work on these light elements, but contains sections on Big Bang nucleosynthesis of Li and the rarity of these light elements. It includes information on how they are observed, both historically and currently, and the difficulties entailed in determining their abundances. %It traces the evolution of these elements through the history of the Galaxy. The production of Li, Be, and B is ongoing so the youngest stars contain the most Li, and they have had less time to destroy it. All three elements are readily destroyed in stellar interiors, but have differing degrees of susceptibility to the particular nuclear fusion reactions which deplete their surface content. This feature makes them remarkably good probes into the otherwise unobservable interiors of stars. It also enhances the use of two or more of the three in sorting out the various processes at work in the insides of stars.
