Extinct Radioactivities: Trapped Residuals of Presolar GrainsThe Astrophysical Journal
PublisherThe American Astronomical Society
AbstractThe xenon anomalies trapped in meteorites and the moon may have first been trapped in circumstellar grains formed in or outside of postexplosive stars. In that case, the initial solar nebula need not have contained most of their radioactive progenitors, and this would necessitate major revision of the history of solar system formation.
