Why would the FET explanation be different from the RET explanation? 
In RET, the solar wind consists of parrallel rays, in FET it radiates from a small object.
In RET the solar wind comes from fusion, in FET the sun has insufficient mass to produce the pressures and temperature needed for fusion (we know this because we can't detect a significant change in gravity as the sun moves overhead).
In RET the Earth's magnetic field resembles that of a bar magnet with the with the magnetic poles roughly under the geographic poles. In FET this is not the case (there is no south geographic pole).
Can we have a diagram of how FE solar wind interacts with the FE magnetic field to produce aurora in the observed places?
I also fail to see how you can postulate that the FE sun doesn't emit solar particles. Haven't we observed them?
We have, which is good evidence against FET because it can't explain the origin of these particles.
