银河系中的锂工厂:新星和AGB星

Lithium factories in the Galaxy: novae and AGB stars

F. D'Antona, P. Ventura

摘要:

我们回顾了最先进的建模锂生产,通过卡梅隆-福勒机制,在两个恒星网站:在新星爆炸和大规模渐近巨星分支(AGB)恒星的信封。我们还展示了有关超级AGB的锂产量的计算的初步结果,并认为金属丰度接近太阳的超级AGB可能是最重要的银河系锂生产商。最后,我们讨论了锂丰度可能有助于理解的方式形成的“第二代”恒星的球状星团。

英文摘要:

We review the state of the art in modelling lithium production, through the Cameron-Fowler mechanism, in two stellar sites: during nova explosions and in the envelopes of massive asymptotic giant branch (AGB) stars. We also show preliminary results concerning the computation of lithium yields from super-AGBs, and suggest that super-AGBs of metallicity close to solar may be the most important galactic lithium producers. Finally, we discuss how lithium abundances may help to understand the modalities of formation of the "second generation" stars in globular clusters.
