| Abstract: | HD 75767 is a sixth-magnitude solar-type star for which Sanford gave an orbit in 1931 on the basis of 37 low-dispersion Mount Wilson spectrograms. The orbit has a period of 10 days and was attributed a small eccentricity. During the last few years the radial velocity of the object has been measured photoelectrically on 60 occasions, allowing the orbital elements to be considerably refined; the eccentricity is shown to be very close (and quite likely equal) to zero. |
