Sorry Antoniseb, can't help you with another mechanism just yet. I wouldn't be surprised if another mechanism exists, but apart from the Electric Model (see other threads for it's discussions and debunking), I don't know of any. Doesn't mean that the spinning assumption is true though, I'd like to see better evidence then pulses (millisecond pulses because of rotation seems like a ludicrous idea to me), or some way to verify collapsed matter experimentally before I accept neutron stars as composed of "neutronium".
We're drifting away from the Iron Sun model, of which I'm still unsure why the measured isotopic ratio's must mean that there is something wrong with what we know of stellar evolution and the history of the Solar System.
Maybe it would be helpful if we compared the 2 models step by step, then maybe I'll be able to see at what point the models diverge, or if there is even anything compatible at all.

Cheers.
