标题： Two Kerr black holes with axisymmetric spins: An improved Newtonian model for the head-on collision and gravitational radiation

摘要： 我们提出一种半解析方法，研究两个（最初）克尔黑洞通过正面对撞过程的相互作用。 从爱因斯坦场方程的一个精确解中推导出引力辐射发射率的表达式。 计算了该过程中发射的引力辐射总量，并与当前的数值研究进行比较。 我们发现自旋-自旋相互作用会使引力波能量的发射增加至总静止质量的0.2%。 我们还讨论了黑洞之间自旋交换的可能性。 显示英文摘要

摘要： We present a semi-analytical approach to the interaction of two (originally) Kerr black holes through a head-on collision process. An expression for the rate of emission of gravitational radiation is derived from an exact solution to the Einstein's field equations. The total amount of gravitational radiation emitted in the process is calculated and compared to current numerical investigations. We find that the spin-spin interaction increases the emission of gravitational wave energy up to 0.2% of the total rest mass. We discuss also the possibility of spin-exchange between the holes.
