Abstract
Resolved spectroscopic binaries are unique among other types of binaries. They provide the only possibility (aside from trigonometric parallaxes) to accurately determine distances to objects, which is one of the most important characteristics in astronomy. Such binaries are not numerous, but an exhaustive catalog of them still does not exist. The authors have developed a pilot version of a new catalog of resolved spectroscopic binaries. It contains information about orbital elements, component masses, parallaxes, and other parameters for 107 stars. Thus, the catalog represents the most extensive list of resolved spectroscopic binaries known to date. A preliminary analysis of the distributions of the stellar parameters of the objects in the catalog has been carried out, as well as a comparison of the trigonometric parallaxes from Gaia DR3 with the orbital parallaxes. The article is partly based on a report presented at the conference “Modern Stellar Astronomy-2022,” which was held at the Caucasian Mountain Observatory of the Astronomical institute of Lomonosov Moscow State University on November 8–10, 2022.
