论文摘要
我们计算由紧凑型二进制系统在一类无质量标量调整器（ST）理论中产生的引力波，以超出标准四极辐射（GR）的标准四极辐射。使用并适应了ST理论，最初在GR中定义的多极 - - 斜 - 纽顿形式主义，我们获得了与ST理论中偶极子辐射相关的尾巴和非线性记忆项。紧凑型二进制文件的多极矩和GW通量是针对包括新的1.5pn贡献在内的一般轨道的，并且与文献中先前的结果进行了比较。对于准圆形轨道，我们提出了用于检测器数据分析的现成模板，并且首次使用标量GW模式进行比较与数值相对性结果进行比较。
We compute the gravitational waves generated by compact binary systems in a class of massless scalar-tensor (ST) theories to the 1.5 post-Newtonian (1.5PN) order beyond the standard quadrupole radiation in general relativity (GR). Using and adapting to ST theories the multipolar-post-Minkowskian and post-Newtonian formalisms originally defined in GR, we obtain the tail and non-linear memory terms associated with the dipole radiation in ST theory. The multipole moments and GW flux of compact binaries are derived for general orbits including the new 1.5PN contribution, and comparison is made with previous results in the literature. In the case of quasi-circular orbits, we present ready-to-use templates for the data analysis of detectors, and for the first time the scalar GW modes for comparisons with numerical relativity results.
