AGB星是这一过程的主要组成部分。在这里，我们讨论了众所周知的属性和仍然存在很大不确定性的属性。在前一种情况下，我们相当肯定，AGB星的过程贡献来自质量在1 ~ 3 μ msun之间的恒星，主要的中子源是C，n）O反应。在后一类中，仍然是C-口袋的形成机制。试图包括旋转似乎抑制中子俘获反应。解释观测结果似乎需要一个C口袋大小的传播，因此必须涉及一些随机过程，如旋转。
AGB stars are the source for the main component of the-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-process contribution from AGB stars comes from masses between about 1 and 3 $\msun$, and the dominant neutron source is theC,n)O reaction. In the latter category remains the formation mechanism for theC-pocket. Attempts at including rotation seem to inhibit neutron capture reactions. Explaining the observations seems to require a spread in the size of theC-pocket so some stochastic process, such as rotation, must be involved.
