论文摘要
最新的关于提高极端质量比的计算效率的工作产生了通过粒子扰动(PP)方法和数值相关(NR)的可比较质量质量比较的有用副产品。在这里我们指出:(1)在选择群众的重新缩放时,必须考虑PP和NR方法的差异,即使是最早的,最少的非线性制度;特别是必须解决Barycenter效应。 (2)必须注意PP中的非钳制残留物和NR中快速旋转的残留物的比较。
Recent work on improved efficiency of calculations for extreme mass ratio inspirals has produced the useful byproduct of comparisons of inspirals of comparable mass by particle perturbation (PP) methods and by numerical relativty (NR). Here we point out: (1) In choosing the rescaling of the masses, consideration must be given to the differences in the PP and NR methods even in the earliest, least nonlinear regime; in particular barycenter effects must be addressed. (2) Care must be given to the comparison of the nonspinning remnant in PP and the rapidly spinning remnant in NR.
