摘要
Orbits are given for four more of the binaries discovered in the Yoss/Griffin radial-velocity survey of all the late-type HD stars north of Galactic latitude b = 75 degrees. The orbits all have quite long periods by the standards of spectroscopic binaries - they are about 7, 10, 24, and 12 years, respectively - and they are all of moderate eccentricities.
