abstract:
We study the tidal stripping of a white dwarf by a black hole. An accretion disk (AD) is formed. We implement the full quantum hydrodynamic equations and carry out numerical simulations to look at the process of creation of the disk. The model of a white dwarf star is a Bose-Fermi droplet of attractively interacting degenerate atomic bosons and fermions.
During the creation of the AD, the falling matter becomes fragmented due to nonlinear effects. Additionally, quantised vortices present in the bosonic component of the accretion disk are observed. They could be responsible for the X-ray flickering noise.
Gravitational radiation generated during the process of the white dwarf tidal stripping is also investigated.
