摘要：
This paper briefly reviews key aspects concerning the evolution and nucleosynthesis of low mass stars both in the disc and in the halo. Low mass stars contribute to the cosmic production of C and most of the heavy neutron capture elements through the s-process. The s-process nucleosynthesis occurs during the thermally pulsing asymptotic giant branch phase (TP-AGB), while the star looses its whole envelope by efficient stellar winds. We will discuss significant examples of different classes of s-enhanced stars and compare the high-resolution spectroscopic observations with theoretical AGB models.
