论文摘要
我们研究了来自极端质量比灵感的重力波的光标度磁场的烙印 - 具有很大质量不对称性的二元系统。我们首先表明，对于质量比的领先顺序，标量对波形的任何效果都是由两个参数完全捕获的：标量的质量和次级紧凑型对象的标量电荷。然后，我们使用这个理论不足的框架来表明，丽莎的未来观察结果将能够以足够的精度同时测量这两个参数，以检测超光量表。
We study the imprint of light scalar fields on gravitational waves from extreme mass ratio inspirals -- binary systems with a very large mass asymmetry. We first show that, to leading order in the mass ratio, any effects of the scalar on the waveform are captured fully by two parameters: the mass of the scalar and the scalar charge of the secondary compact object. We then use this theory-agnostic framework to show that the future observations by LISA will be able to simultaneously measure both of these parameters with enough accuracy to detect ultra-light scalars.
