摘要
We update the analytical estimate of the final spin of a coalescing black-hole binary derived within the effective-one-body (EOB) approach. We consider unequal-mass nonspinning black-hole binaries. It is found that a more complete account of relevant physical effects (higher post-Newtonian accuracy, ringdown losses) allows the analytical EOB estimate to "converge towards" the recently obtained numerical results within 2%. This agreement illustrates the ability of the EOB approach to capture the essential physics of coalescing black-hole binaries. Our analytical approach allows one to estimate the final spin of the black hole formed by coalescing binaries in a mass range [nu=m(1)m(2)/(m(1)+m(2))(2)< 0.16] which is not presently covered by numerical simulations.
