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 ##IMG## [http://ej.iop.org/images/0264-9381/37/9/095002/cqgab7d80ieqn1.gif] {${\mathcal{M}}_{\mathrm{B}\mathrm{H}}=\frac{Q}{{m}_{\mathrm{B}\mathrm{H}}}\;{S}_{\mathrm{B}\mathrm{H}}$} 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.

黑洞-中子星双星系统中磁对重力波产生的影响

众所周知，浸入磁场中的旋转黑洞可以选择性地增加一个符号的电荷并排斥相反符号的电荷。这会产生以下形式的磁矩：## IMG ## [http://ej.iop.org/images/0264-9381/37/9/095002/cqgab7d80ieqn1.gif] {$ {\ mathcal {M} } _ {\ mathrm {B} \ mathrm {H}} = \ frac {Q} {{m} _ {\ mathrm {B} \ mathrm {H}}}} \; {S} _ {\ mathrm {B} \ mathrm {H}} $}其中Q是黑洞电荷，m BH是质量，S BH是自旋。结果，具有中子星的双星系统中的黑洞会受到星磁场的影响而成为磁偶极子。我们研究了这一事实对黑洞-中子星双星系统发射引力波的结果。
