Scientific paper

The spectroscopic orbit of the G5 supergiant HD 187299 suggests that the
secondary star should be detectable spectroscopically in the
ultraviolet. A Mount Wilson coude spectrogram confirms that expectation;
digital subtraction of the spectrum of the MK standard star 9 Peg (G5
Ib) leaves the spectrum of HD 187299B, a late-B main sequence star.
