论文摘要
为了准备未来的太空传播引力波（GW）探测器，建模工作是否应该集中在高精度真空模板上，还是来源的天体物理环境？我们对由1）气态和恒星物质背景中的已知环境效应引起的相位贡献进行系统的比较，或2）在MHz GW来源的演变中{（在大型二元组的灵感阶段）中，高阶后牛顿后{（pn）}术语。我们使用当前可用的分析波形模型的精度作为基准{值，查找}以下趋势：最大的未建模相位贡献可能是环境的，而不是二进制文件的PN，而不是$ \ sim 10^7/（1+z）^2 $ 〜m $ $ $ $ _ {\ odot} $，其中$ z $是$ z $。二进制比$ \ sim 10^8/（1+z）$ 〜M $ _ {\ odot} $由于低信噪比（SNRS）而不需要更准确的{Inspiral}波形。对于高SNR来源，环境{阶段贡献}在低红移时是相关的，而高级真空模板则在$ z> 4 $时需要。在这些发现的带领下，我们认为应优先考虑在波形模型中包括环境影响，以最大程度地提高未来MHz探测器的科学收率。
In preparation for future space-borne gravitational-wave (GW) detectors, should the modelling effort focus on high-precision vacuum templates or on the astrophysical environment of the sources? We perform a systematic comparison of the phase contributions caused by 1) known environmental effects in both gaseous and stellar matter backgrounds, or 2) high-order post-Newtonian {(PN)} terms in the evolution of mHz GW sources {during the inspiral stage of massive binaries}. We use the accuracy of currently available analytical waveform models as a benchmark {value, finding} the following trends: the largest unmodelled phase contributions are likely environmental rather than PN for binaries lighter than $\sim 10^7/(1+z)^2$~M$_{\odot}$, where $z$ is the redshift. Binaries heavier than $\sim 10^8/(1+z)$~M$_{\odot}$ do not require more accurate {inspiral} waveforms due to low signal-to-noise ratios (SNRs). For high-SNR sources, environmental {phase contributions} are relevant at low redshift, while high-order vacuum templates are required at $z > 4$. Led by these findings, we argue that including environmental effects in waveform models should be prioritised in order to maximize the science yield of future mHz detectors.
