Inserted a brief summary of the review by Siegel on GW170817 and the site of the r-process.

Corrected typo: "r-process in high mass stars (that will become supernovae) dominates the s-process" instead of "s-process in high mass stars ...". Added a word "aforementioned" just so that the system would let me save the Edit.

| Nov 20, 2014 at 12:31 | comment | added | ProfRob | @supercat Sorry for not spotting this earlier. I believe all the stable elements beyond lead are produced almost exclusively in supernova explosions via the r-process. The question about the limits on nuclear size is a different one - possibly already answered on Physics SE - but governed by the properties of the strong, weak and electromagnetic forces. Very heavy and exotic elements may exist briefly in the cores of supernovae before they explode and are probably still present in the crusts of neutron stars. | |
| Nov 5, 2014 at 0:48 | comment | added | supercat | Is there any reason to believe that supernovae stopped at element 92, or even 118? I know there are limits to how large a nucleus can get, but I would think that a supernova would be a lot more powerful than any of the reactors we've used to create trans-uranics. | |
