The present study investigates the electromagnetic and gravitational radiation produced during the tidal stripping process of a white dwarf orbiting a stellar black hole. The white dwarf star is modelled as a Bose–Fermi droplet, and the quantum hydrodynamic equations are employed to describe the dynamics of the produced accretion disc. The quantum matter that falls onto a black hole (BH) after the periastron passage is a source of powerful radiations. The phenomenon of bursts of
electromagnetic radiation bears a striking resemblance to the recurrent flaring of X-ray sources. The phenomenon of gravitational energy bursts is primarily characterised by the emission of low-frequency radiation. Subsequently, the accretion disk begins to contribute to the radiation in a continuous manner.
