The x-rays are not produced because of high heat. I've explained this in simple language.
The x-rays on the sunward side of the cometary nucleus are produced because energy is conserved. When the electric current from the sun reaches the comet it must slow down because the comet is moving very fast -- not sure how fast but probably 20,000 miles an hour at least.
As the electric current slows down it must give up energy - which it does in the form of x-rays.
Incidentally, Dr Dwyer also discovered that lightning also produces gamma rays -- and for the same reason.
I would not be surprised if astronomers find that comets also produce gamma rays -- and by the same mechanism. Maybe they should look.
So your hypothesis it that x-rays are produced from brems-strahlung caused by the impact of solar electrons on the surface of the comet?
If that was the case everything in space should emit the same x-rays including unmanned probes and the moon.
FYI, the speed of the comet is irrelevant, solar electrons move at roughly 90-95% of the speed of light which is 300.000 km/s.
