- Title
Extremely Wide Pairs in the World of Binary Stars.

- Abstract
This article raises the question of the possibility of identifying stellar pairs in which one of the components belongs to the family of near-nuclear central S-stars and the other belongs to a population of hypervelocity stars (HVSs). In the recent past, they could be genetically linked in a single parent binary star (BS), and today its components are separated by hundreds or more parsecs as a result of dynamic capture of a BS by the field of a supermassive black hole (SMBH). There is interest in the mutual reconstruction of populations of S-stars and HVSs calculated in the context of the classical Hills scenario, based on the principle of supplementing their observational data. The paper is based on a report presented at the astrophysical memorial seminar "Novelties in Understanding the Evolution of Binary Stars," dedicated to the 90th anniversary of Professor M.A. Svechnikov.
