摘要：

A rotating star's oblateness creates a deformation in the gravitational field outside the star, which is measured by the quadrupole-moment tenser. We consider the effect of the quadrupole moment on the orbital motion and rate of inspiral of a compact binary system, composed of neutron stars and/or black holes. We find that in the case of circular orbits, the quadrupole-monopole interaction affects the relation between orbital radius and angular velocity, and also the rate of inspiral, by a quantity of order (v/c)(4), where v is the orbital velocity and c the speed of light.
