The AGB star then fades from view, leaving the altered composition of the companion as the only clue to its nucleosynthesis. By studying the companion’s unusual abundances, together with modelling how ...

Stars forge heavy elements by nucleosynthesis ... You might expect that the same collapsing star producing a very energetic and bright GRB would also produce a very energetic and bright supernova.

But grains cast off from young star systems also have a calcium-44 ... Presolar Grains As Probes of Supernova Nucleosynthesis ...
