I've long been rather satisfied with your 2 stellar models of tokamaks and CI, or whatever you're calling sun-like stars now. But I'd be curious if you come up with details about the pulsar fusion sputtering. I mean I'm curious about exactly how that would operate and cause hundreds or thousands of equally timed sputters or pulses per second. Since sputtering is a term for electric discharges, is E.D.s what you mean here too? And do you have data on the exact timing of pulses? It seems like there'd be some variation in the timing of pulses, if they're not due to rotating lighthouse beacons. I guess the same question applies to the Cepheids. Does the data on them show some variation in the time between changes in brightness? Seeing some of the data might be interesting too, if it's displayed clearly somehow.
