论文摘要
爱因斯坦 - 斯卡尔 - 高斯 - 高斯 - 鲍尼特重力理论中黑洞二进制的牛顿后动力学取决于所谓的“敏感性”，这些数量表征了黑洞对同伴所采用的时间依赖性标量环境的绝热响应。在这项工作中，我们在三类的爱因斯坦 - 斯卡尔 - 高斯 - 摩纳网重力中计算非旋转黑洞的敏感性，包括自发标量的敏感性：偏移对称，膨胀和高斯理论。在可能的情况下，我们将结果与扰动分析结果进行比较，找到出色的一致性。与他们的一般相对论对应物不同，爱因斯坦 - 斯卡尔 - 高斯 - 邦纳特重力中的黑洞仅在受理论耦合常数控制的受限制参数空间中存在。对黑洞二进制文件中敏感性扮演的作用的初步研究表明，原则上，黑洞可以在灵感过程中驱动其在其存在域之外，以解决我们确定的二进制参数。
The post-Newtonian dynamics of black hole binaries in Einstein-scalar-Gauss-Bonnet theories of gravity depends on the so-called "sensitivities", quantities which characterize a black hole's adiabatic response to the time-dependent scalar field environment sourced by its companion. In this work, we calculate numerically the sensitivities of nonrotating black holes, including spontaneously scalarized ones, in three classes of Einstein-scalar-Gauss-Bonnet gravity: the shift-symmetric, dilatonic and Gaussian theories. When possible, we compare our results against perturbative analytical results, finding excellent agreement. Unlike their general relativistic counterparts, black holes in Einstein-scalar-Gauss-Bonnet gravity only exist in a restricted parameter space controlled by the theory's coupling constant. A preliminary study of the role played by the sensitivities in black hole binaries suggests that, in principle, black holes can be driven outside of their domain of existence during the inspiral, for binary parameters which we determine.
