It is known that a rotating black hole immersed in a magnetic field can selectively accrete charges of one sign and repel charges of the opposite sign.

Abstract

It is known that a rotating black hole immersed in a magnetic field can selectively accrete charges of one sign and repel charges of the opposite sign. This gives rise to a magnetic moment of the form ${mathcal{M}}_{mathrm{B}mathrm{H}}=rac{Q}{{m}_{mathrm{B}mathrm{H}}};{S}_{mathrm{B}mathrm{H}}$ where Q is the black hole charge, m BH is the mass and S BH the spin. As a consequence, a black hole in a binary system with a neutron star is affected by the star magnetic field as a magnetic dipole. We study the consequence of this fact on the emission of gravitational waves by a black hole-neutron star binary system
