If the angular distance between the components of a binary star is less than 0.05 “, then they are not resolved even in the most powerful telescopes. Suggest a method for detecting the binary star.
Such stars can be detected by the periodic shift of lines in their spectra, which arises from the Doppler effect. The method is not applicable if the orbital plane lies in the sky plane.
