Description
In this poster we will present our study on the scattering of boson-star binaries, taking into account
three effects: point-mass gravitational, tidal, and short-range
scalar-field interactions. We compare analytical results to the
scattering angle extracted from four sequences of numerical-relativity
simulations at fixed energy and varying impact parameter. The
agreement is very good and exhibits the attractive (repulsive)
effect of in-phase (out-of-phase) binaries. For small impact
parameters, where the stars approach more closely before separating
to infinity, the short-range scalar-field interaction is found to
dominate.
