  Recent detections by the gravitational wave facilities LIGO/Virgo have opened
a window to study the internal structure of neutron stars through the
gravitational waves emitted during their coalescence. In this work we explore,
through numerical simulations, the gravitational radiation produced by the
merger of binary neutron stars with dark matter particles trapped on their
interior, focusing on distinguishable imprints produced by these dark matter
cores. Our results reveal the presence of a strong m = 1 mode in the waveforms
during the post-merger stage, together with other relevant features. Comparison
of our results with observations might allow us to constraint the amount of
dark matter in the interior of neutron star.
