Scientific paper

A new method of determining stellar masses is proposed, based on interferometric observation of the relativistic deflection of light beams from close optical binaries. If the true relative trajectory of two stars seen from earth is a straight line, the apparent trajectory will deviate from a straight line, the deviation being greater as one approaches the instant of closest encounter of the two stars. This deviation is the basis of the calculation of mass. It is estimated that there are at least around 20 optical binaries on which to test the method.
