Nucleosynthesis in AGB Stars | Maurizio M
To investigate the effect of a companion star on stellar evolution the code was developed. The code uses the BSE package at its core, with nucleosynthesis in parallel, to explore large parameter spaces in reasonable periods of time. Mass lost from the binary system contributes to the and since the BSE code is based on the SSE code nucleosynthesis for populations of single stars is also calculated. The two are then compared to see if there is any difference.
Binaries are important:
Binary evolution is plagued with uncertainy, even compared to our understanding of single-star evolution.
Effects which must be considered include:
Neutron-capture Nucleosynthesis in the First Stars
that stars fuse light atomic nuclei to create heavier nuclei. Elements in the universe heavier than hydrogen (but lighter than iron) are created by a process known as stellar nucleosynthesis: nuclear reactions . But it has been a long-standing mystery as to where in the universe elements heavier than iron are synthesized, researchers said in from the Max Planck Institute for Astrophysics (MPA) in Germany.
()Recent studies suggest that metal-poor stars enhanced in carbon butcontaining low levels of neutron-capture elements may have been amongthe first to incorporate the nucleosynthesis products of the firstgeneration of stars.
