Episode notes

The dwarf galaxy is still intact today. So nothing crazy could have happened. Probably some heavy elements come out of supernovae here and there. But somehow my theory colleagues tell me that the normal supernova just doesn't have enough oomph to really get an R process going, right? And so you need these orbiting supernova. We need them the probably the neutron star mergers or we need a special kind of supernova that's maybe extremely massive or heavily rotating or does something else funny,. Right? To really kind of get that particular process going. The data I got for that was insanely good. It yielded this uranium detection and thorium detection. You can never get that kind
