| Abstract: |
Supernovae eject material into the interstellar medium that is highly heterogeneous and highly non-solar in isotopic composition. In contrast, calcium-aluminum-rich inclusions (CAIs) in primitive meteorites have isotopic compositions that are very similar to those of the bulk Earth and Solar System and, for most elements, to each other. Thus, a recent suggestion that CAIs formed originally as supernova condensates is untenable. |
