For some completely irrational reason I was slightly disappointed that the gold in my wedding ring was only from a neutron star merger and probably not from a supernova.

However, reading the relevant wikipedia page I came across this part:

"this single neutron star merger event generated between 3 and 13 Earth masses of gold"

https://en.wikipedia.org/wiki/Gold#Gold_production_in_the_Un...

Can't wait to refer to that in the next discussion on HN about gold as a store of value.... ;-)

While the neutron-star merger suggested that a substantial fraction of the r-process occurs in neutron stars, it does not rule out the possibility that the r-process also occurs in supernovae (the other leading candidate).

I'd be happy to wager that at least a couple percent of your wedding ring's nuclei were formed in a supernova.

Neutron Star Mergers & Acquisitions sounds like a great title for book or TV show.

I have a very-soon-merging neutron star pair to sell to you.

"You want to be on the ground floor of this IPO because I'm telling you it's going to just be exploding gold (and other elements)."

Radioactive gold, at that.
