Apparent Lack of Symmetry.
A serious problem is revealed when one reads the description of that phenomenon. Scientific papers and textbooks on relativity [6] state or imply that stellar aberration is determined by the "relative velocity" between the light source and the detector. It has been clearly shown experimentally that it is not so. Many convincing arguments have been pointed out by H. Ives [2], Eisner [3], and Phipps [4], and Hayden [5], and several others to show that when the source (instead of the detector) is moving, the aberration no longer exists. Observations show clearly that, in contradiction with special relativity, stellar aberration does not depend on the relative motion between the source and the detector but exists only when the detector is moving. Textbooks explain the results solely when the observer is moving. There is no known explanation for the case when the source is moving.
That lack of symmetry, between the cases whether the source or the detector is moving is shown clearly [5] on the basis of the separation of binary stars. One can reliably determine the motion of individual stars of a binary system from their spectrum from the periodic Doppler shifting of the spectral lines of the star components. Therefore, stars of a binary system acquire sufficient relative transverse velocity to produce an important aberration. Such an aberration is not observed. Some papers report non realistic hypotheses to explain aberration when the star is moving. The explanation goes from the claim that we do not observe reality or the "Umbrella Analogy" mentioned by Eddington and some others.
