I think the electrons emit photons as a result of decelerating which is caused by the magnetic field (which can influence the charged electron). And I’ve never actually pondered whether a proton changing its direction due to gravity (technically decelerating along its original path and accelerating along its new path) would emit photons. I don’t think it would because from its frame of reference it’s not accelerating… I need to do some homework, very interesting! Edit: It seems a charged particle accelerating due to gravity will not emit photons. See https://www.mathpages.com/home/kmath528/kmath528.htm https://www.mathpages.com/home/kmath528/kmath528.htm
