Wasn't the accepted model that formation of these happens only in supernova events?

- Sharlin 3y agoThe article is talking about the r-process, so it’s still supernovas (either core-collapse or more likely neutron star collision) that would have forged these elements. Ancient or not, a stably burning star isn’t going to synthetize nuclei heavier than iron in non-negligible quantities.
- antognini 3y agoSome elements are believed to only form from neutron star mergers.
