Title: “Simulations of Hypervelocity Star Motion in the Gravitational Field of Binary Black Hole”
Abstract: We perform numerical simulations of single star motion in the gravitational field of a binary black hole with different mass ratios of components. We consider the general three-body problem. The model is applicable to all times except the close encounters of a star with one of the components of the binary r < 0,00002 pc, where r is the distance from the star to the nearest black hole. At the closer passages one should take into account the relativistic corrections. We have found the estimations of the probability of formation of hypervelocity stars as a result of such interactions. We consider the application of the results to a double black hole in the nucleus of galaxies.
