FIZIKA 3/2/1 2021 - 358 - Moreover, when 𝑗 > 𝑗 𝐺𝐽 the Lorentz factor tells about repeating radiation in the form of pulses continiously at close distances to the surface of the neutron star. The distance become shorter in the presence of both aether parameters, while the effect of 𝑐 14 parameter is stronger than the effect of parameter 𝑐 13 . In both panels, it is seen that at large distances the Lorentz factor grows very slowly and reaches its saturation value.
