Title: Gravitational Waves from Stellar Black Hole Binaries and the Impact on Nearby Sun-like Stars,
Abstract: We investigate the impact of resonant gravitational waves on quadrupole
acoustic modes of Sun-like stars located nearby stellar black hole binary
systems (such as GW150914 and GW151226). We find that the stimulation of the
low-overtone modes by gravitational radiation can lead to sizeable photometric
amplitude variations, much larger than the predictions for amplitudes driven by
turbulent convection, which in turn are consistent with the photometric
amplitudes observed in most Sun-like stars. For accurate stellar evolution
models, using up-to-date stellar physics, we predict photometric amplitude
variations of $1$ -- $10^3$ ppm for a solar mass star located at a distance
between 1 au and 10 au from the black hole binary, and belonging to the same
multi-star system. The observation of such a phenomenon will be within the
reach of the Plato mission because telescope will observe several portions of
the Milky Way, many of which are regions of high stellar density with a
substantial mixed population of Sun-like stars and black hole binaries.
