Christ the swarm is out! Now fly & come here my cattle. In the Lord’s peace; in the protection of God; come home in good health. Sit, sit, bees, St Mary impels you. You have no furlough. Do not fly into the woods. Neither will you escape me nor will you elude me. Sit... still; work God’s will.

At that range of semimajor axes, it's starting to overlap the protoplanetary disk gap population very nicely as well!

We can also make predictions for what we will be able to see if we have better stellar mass measurements: as Gavin points out, with those, it becomes possible to determine how important magnetohydrodynamic winds are for removing angular momentum from a disk.

The idea here was to take Gavin's large grid of disk models (which includes all kinds of physics for disk evolution, and crucially external photoevaporation), and see how the median disk mass evolves with external UV. It matches up really well to observational data in Orion: the environment matters!

I think adding stakes would make it a ho-ho, per Pratchett, but I am not a landscape architect.

Another argument against these things is that, if someone else's missile defense is 90% effective, you have no reason to not try it anyway and maybe blow up just one major city instead of ten, lowering the barrier to a nuclear exchange between superpowers.

It's lovely (and reminded me that everyone should know the doors to the Pantheon in Rome are, likely, the original bronze slabs (with later decoration) from 126ish).
