  We calculate the neutrino luminosity in an astrophysical scenario where dark
matter is captured by a neutron star which eventually implodes to form a low
mass black hole. The Trojan horse scenario involves the collapse of a neutron
star (NS) due to the accumulation of a critical amount of dark matter (DM)
during its lifetime. As a result, a central disk forms out of the ejected
material with a finite radial extension, density, temperature, and lepton
fraction, producing fainter neutrino luminosities and colder associated spectra
than found in a regular core-collapse supernova. The emitted gravitational wave
(GW) signal from the imploding NS should be detectable at ultra-high $\gtrsim
0.1$ GHz frequencies.
