摘要:Our recent 3D simulation of a supernova explosion to constrain the progenitor of Cas A has
enabled us to gain new insight into burning processes at work. Of special interest in this poster are
the isotopes 26Al, 16O, 17O, and 18O. These isotopes are important in the formation history of our
solar system, and help constrain its environment at the time of formation. A favored model is the
addition of supernova ejecta to the forming solar system, which presumably changed the isotopic
abundances of a range of isotopes (like those mentioned above). In this poster we investigate how
the relative abundances of the oxygen isotopes in the solar system is affected by the injection of
supernova material, given that this injection produces the expected change in 26Al/27Al. We also
investigate whether the bulk composition or specific zones of the supernova are more appropriate,
and what the determining factors are. Lastly, we look at differences between 1D and the 3D
simulation in this matter.
