标题： What we do and do not know about the s-process

摘要： AGB 恒星是主要成分的来源$s$-过程。 在这里我们讨论那些相当清楚的性质以及那些仍然存在很大不确定性的性质。 在前者的情况下，我们非常确定 AGB 恒星的$s$-过程贡献来自大约 1 到 3$\msun$的质量范围，主要的中子源是$^{13}$C$(\alpha$,n)$^{16}$O 反应。 在后一类中仍然是$^{13}$C-口袋的形成机制。 尝试包括旋转似乎会抑制中子俘获反应。 解释这些观察结果似乎需要$^{13}$C 口袋大小的变化，因此必定涉及某种随机过程，例如旋转。 显示英文摘要

摘要： AGB stars are the source for the main component of the $s$-process. Here we discuss both the properties which are reasonably well known and those which still suffer from substantial uncertainties. In the former case, we are fairly sure that the $s$-process contribution from AGB stars comes from masses between about 1 and 3 $\msun$, and the dominant neutron source is the $^{13}$C$(\alpha$,n)$^{16}$O reaction. In the latter category remains the formation mechanism for the $^{13}$C-pocket. Attempts at including rotation seem to inhibit neutron capture reactions. Explaining the observations seems to require a spread in the size of the $^{13}$C-pocket so some stochastic process, such as rotation, must be involved.
