Abstract:
We study the scattering of two boson stars by comparing four sequences (at fixed energy and varying impact parameter) of numerical relativity simulations to an effective-one-body analytic description, taking into account both gravitational effects (point-mass and tidal) and short-range scalar-field interactions. We obtain excellent agreement between analytical and numerical results, exhibiting the importance of short-range scalar-field interactions for small impact parameters. Our Letter paves the way toward analytic waveform templates of exotic compact object binaries.

Schwarzschild Radius and Event Horizon
The minimum speed required to launch a projectile from the surface of an object to which it is gravitationally bound so that it eventually escapes the object’s gravitational field is called the escape velocity. The escape velocity is independent of the mass of the object. Merging the idea of escape velocity with the...
