摘要：Models of rotating stars at Z = 5×10−4 and 10−5 with masses between 2.5 and 7 M
⊙
are computed
from the pre-main sequence up to the end of the asymptotic giant branch phase (AGB).
We discuss the impact of rotation on nucleosynthesis. We show that it plays a major role during
the phase of central He-burning. Rotational-induced mixing transports indeed freshly produced
carbon and oxygen into the H-burning shell where some new primary elements are synthesized.
In the most massive early-AGB stars, those elements are revealed at the surface during the second
dredge-up event. We also follow the changes in surface and wind composition due to the interplay
between third dredge-up and hot bottom burning during the TP-AGB phase. We present the final
stellar yields and discuss our predictions in the context of the chemical anomalies seen in galactic
globular clusters.
