Abstract: | Photoelectric radial-velocity observations, begun independently at Cambridge and at Ames by the respective authors and now including results from no fewer than six radial-velocity spectrometers, show that the K1 III star HR 4793 is a spectroscopic binary; it has a circular orbit with a period of 111 days and the quite modest amplitude of 7kms-1 |
