| Summary:
Gravitational-wave signals detected to date are commonly interpreted under
the paradigm that they originate from pairs of black holes or neutron stars.
Here, we explore the alternative scenario of boson-star signals being present
in the data stream. We perform accurate and long ($sim 20$ orbits) numerical
simulations of boson-star binaries and inject the resulting strain into LIGO
noise. Our Bayesian inference reveals that some boson-star signals. are
degenerate with current approximants, albeit with biased parameters, while
others exhibit smoking-gun signatures leaving behind conspicuous residuals.
