论文摘要
二进制中子星结合的重力波（GW）检测对于限制超高密度的物质相互作用起着至关重要的作用。同样，如果玻色子恒星存在于宇宙中，则可以使用合并来限制标量场理论的基本耦合常数。我们开发了具有四分之一相互作用的玻色子恒星灵感的第一个相干波形模型。波形包括一致的自旋诱导的四极性和潮汐性贡献，其性贡献在二进制的质量和旋转方面以及该理论的单个耦合常数。我们表明，未来的仪器（例如爱因斯坦望远镜和激光干涉仪空间天线）可以在玻色粒自我相互作用上提供强烈的互补界，而当前检测器的约束功率则是边缘的。
Gravitational-wave (GW) detections of binary neutron star coalescences play a crucial role to constrain the microscopic interaction of matter at ultrahigh density. Similarly, if boson stars exist in the universe their coalescence can be used to constrain the fundamental coupling constants of a scalar field theory. We develop the first coherent waveform model for the inspiral of boson stars with quartic interactions. The waveform includes coherently spin-induced quadrupolar and tidal-deformability contributions in terms of the masses and spins of the binary and of a single coupling constant of the theory. We show that future instruments such as the Einstein Telescope and the Laser Interferometer Space Antenna can provide strong complementary bounds on bosonic self-interactions, while the constraining power of current detectors is marginal.
