Over the last week we had a lot of news about nova - here, smallscale. Normal nova makes cosmic rays although, not such as irradiated holes into the Mir station over here. This was RS Ophiuchi; CK Vulpeculae being a kilonova, of two big neutronstars.
On the small side of the nova, meet the micronova. Apparently some dwarfs have magnetic fields. As they steal mass from their companions their magnets funnel the mass up to their poles. These go boom with a million times less mass than the usual, hence "micro". I expect they go boom more frequently also, and they'll probably never do the full nova as long as the magnets are up. As for cosmic rays we might not even see these.
I am somewhat surprised we don't see more, but they are harder to spot from over here.
