Pulkovo catalog of relative positions and motions of visual double and multiple stars from photographic observations with the 26-inch refractor in 1960-2007

Kiselev, A. A.; Romanenko, L. G.; Kiyaeva, O. V. +7 more

The results of long-term, uniform, photographic observations of visual double and multiple stars obtained on the Pulkovo 26″ refractor are presented. Relative positions are calculated for 259 pairs of visual double stars in 194 systems, with the relative motions also computed for 127 pairs. Lower limits for the total masses of the systems for whic…

Orbits of four visual binaries determined from observations along short arcs

Kiselev, A. A.; Romanenko, L. G.

The orbits of the four visual binaries ADS 246 (GL 15), ADS 7724 ( γ Leo), ADS 10386 (GJ 659), and ADS 14909 (1 Peg) have been determined using the apparent motion parameters (AMP) method. The orbital periods of these stars are 1200, 550, 7500, and 18 000 yr, respectively. The orbits were calculated based on observations along short arcs obtained …
