The foundations of stellar nucleosynthesis have been established more than 70 years ago. Since then, much progress has been made, both on the theoretical side, with stellar evolution and nucleosynthesis models of increasing complexity, using more and

Neutron stars are possible end products of massive star evolution (M ≥ 8 Msun). They are exotic astronomical objects observed with masses between 1.2 and 2.35 Msun and typically emitting at radio and X-ray wavelengths, especially when being young a

S stars are late-type giants that are transition objects between M-type stars and carbon stars on the asymptotic giant branch (AGB). They are classified into two types: intrinsic or extrinsic, based on the presence or absence of technetium (Tc). The
