The hypervelocity stars recently found in the Galactic halo are expelled from the Galactic center through interactions between binary stars and the central massive black hole or between single stars and a hypothetical massive binary black hole. In this Letter, we demonstrate that binary stars can be ejected out of the Galactic center with velocities up to 103 km s-1, while preserving their integrity, through interactions with a massive binary black hole. Binary stars are unlikely to attain such… Expand
