I was thinking about this and parts of this and I just realized an obvious implication of this situation.

Say that your standard supernova has a serious effect on worlds within fifty light years and a noticable one at twice that distance (as in Pompe's example). The average separation between stellar systems in our next of the woods is about five light year so about a thousand stars would fall within the first class and about ten thousand in the second class, per supernova. There may have been up to twenty supernova, which seems to me to might that up to twenty thousand systems would have been within fifty light years and up to two hundred thousand within one hundred light years of a supernova (or less, depending on how the killzones overlapped).

On Earth, recovery after a major extinction events takes millions of years. Here we could have thousands, perhaps tens of thousands of worlds of various kinds that have subjected to similar highly stressful events in the last ten million years, recently enough for complex ecosystems to still be rebounding. That's worth a look, I think.

The main problem is that a lot of those stars will have covered a fair amount of distance since the chain of supernovas. I wonder if there's an obvious set of candidates to examine?
