I think the main issue it's that they would need to be made in sufficient quantity to show up in the Spectra of the novas and collision. The heavier they are the fewer will be made, making detection harder and harder. You'd also need to calculate all the lines for a given element at the various energy levels to determine if a set of lines match, and that gets nontrivial pretty quickly

I think that that issue is secondary to the fact that the island of stability has predicted half-lives in the range of a year or two. So in order to look for that spectrum we have to have supernovae that have happened very recently and close enough for us to make out the spectrum in what remains.

I hadn't seen anything saying a year or two, I think I've only seen predictions on the orders of hours to days which would basically make it impossible to detect on anything that could be reasonably close to us since they'd be around for such a short time and only during/after the brightest part of the whole thing.

Ah, that makes sense. Thank you.
