Doesn’t always have to be electricity, even condensed matter has a cyclicity.
I realize standard impactors during the catastrophe has been something of a contentious topic in the SO community for some time, but I’m really glad to see papers like this showing up here. I’ve always held an increase in frequency of impactors is part and parcel of the catastrophe, the 2k or so years following the crescendo will see a marked uptick in impactors/airbursts due to the rearranging of debris in our solar system. We see nearly every planet in the system giving signs of changes in their electromagnetic character (plutos atmosphere, uranus’ flaring, etc, you know the list), the smaller bodies in our system are no different, and are affected by the changes in the planets and the sun. The Jovian Trojans in particular should take only small disturbances at Jupiter to begin flinging them out at what may as well be random directions (I believe you covered a paper on this very topic recently). There is also the micronova itself, we already calculate for the drift in orbit caused by radiative heating on a non-uniform body, that blast of energy will disturb a lot of material. I think Ceres is one we should keep a close eye on; an activation, surge, or change in magnetism or orbit there could massively disturb the main asteroid belt and potentially wreak havoc on our own peaceful orbit. We will almost certainly have up to a couple millennia of clearing some of these newly dislodged objects from our orbit, just how much is the question.
I don’t think there will ever be as solid of a timeline on impactors as there is on say volcanic eruptions or magnetic excursions; for one, most of the planet is water and there simply isn’t the record to create the timeline from; secondly, where the record does it exist it is marred by erosion, sedimentation, and obfuscation by solar influence (unreliability in dating, confusion where particular ions or elements came from). We won’t make real sense of the timeline we do have until we recognize it appears cyclical because it is, due to the micronova; it is a pattern of disturbance, clearing, peace. If we want a more detailed timeline of the catastrophe(s) itself, we need to look much more closely at the places we see both the fine broad spray of ions and small material from the solar micronova and large impact craters. One overlays the other, if only by a handful of years, and the evidence from the ~12kya event is still fresh enough in some places (Greenland) we could likely determine this, determining the gap between the two would be even better, though unrealistic with dating techniques. Just how long do the catastrophe(s) drag on before we clear the turning of the cycle(s)..
