Abstract

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