  • 摘要:Orbits of 44 close and fast visual binaries are computed using the latest speckle observations; 23 orbits are determined for the first time, and the rest are revisions, some of those substantial. Six combined orbits use radial velocities. The median period is 15.6 years, and the shortest period is one year. Most stars are nearby late-type dwarfs. Dynamical parallaxes and estimates of the masses are derived from the orbital elements and the photometry of the components.
