Question

Does the gravitational Doppler effect affect charge?

Answer 1

I know that the charge of objects large enough to have distinct gravity is for the most part irrelevant, but large bodies do have (at a given instant) a fixed charge, which, granted, might be hard to read given magnetic fields and charged magneto-spheres, but say that a very massive object, high gravity object, a white dwarf or neutron star, has a defined charge. Is that charge weakened by the gravitational Doppler effect?

I assume it is weakened because I don't see why it wouldn't be, but I tried looking up the answer using google without success. If the answer is yes, is there a name for this. At my level of education, a layman's explanation is a plus.

Answer 2

It's easy to get confused but assuming you mean a gravitational wave, like the primordial gravitational waves recent proven at Harvard and Stanford (are these the two schools who deserve credit? Perhaps there is many more) Gravitational blueshift can be detected as a reddening of photons coming from a gravity well and unlike apparent Doppler blueshift, it doesn't matter what angle the observer observes. Having said that  these waves are treated like electromagnetic waves in some aspects with c = λ f as the speed, wavelength frequency but detection requires interferometry and paying close attention to numbers that are not quite right with photos and momentum and orbital decay and so on.
