LR, as used here, is an updated version of the original LET (Lorentz Ether Theory). The older theory postualted a universal particle field that was uniform. The updated version sees a 'universal' particle field that is influenced by gravitational force like other forms of matter. The particles are small enough that we canot presently detect them. Some estimates place them at about 10^-3 to 10^-6 electron masses. The field is more dense near massive objects like atoms and stars, less dense in the voids between.
This variation in density near matter is analogous to the 'bending of space-time' in GR. The equations that come from this view of the universe are essentially identical to the equations of GR. In DRP (Deep Reality Physics), the variable density particle field turns out to be the physical embodiment of the gravitational potential field of a mass. It is also the medium through which EM radiation propagates. (Note that gravitational force is a physically distinct phenomenon, with a different physical cause, and that in DRP force generates potential rather than the other way round as in some other theories.)
The particle field has a not quite zero interaction with matter. Small enough that we do not notice any drag over the time we have been looking. (Other observations, combined with logic, actually place a lower constraint on the size of this interaction.) But not zero, and over time the particle field near a mass assumes the motion of that mass. So it is not surprising that a central mass would have one effect on an orbiting body if it is rotating, and another effect if it is not. The differences, of course, should be minute.
