Description
We propose a new site for neutron-capture process in massive metal-free and metal-poor stars during the late stages of their evolution. We find that a wide range of neutron-capture abundance patterns can be produced which can explain origin of neutron capture elements observed in many metal-poor stars including CEMP-s, CEMP-rs, and CEMP-no stars. This can fundamentally change our understanding of the origin of heavy elements as well as the evolution of the early Galaxy and the nature of first stars.
