论文摘要
使用有效的场理论(EFT)方法,我们计算地平线耗散对相对论二进制黑洞系统的重力相互作用的影响。我们假设动力学是扰动的,即它承认牛顿常数的力量(后者后或PM,近似值)的扩展。作为应用,由于对领先的PM顺序的耗散效应以及纽顿后(PN)的校正,我们对黑洞碰撞中的散射角进行了校正,并校正了非权利性轨道中二进制黑洞的运动方程,这代表了运动方程中领先的有限大小效应。这里开发的方法也适用于更通用的紧凑对象的情况,例如。中子恒星,其中耗散作用的大小取决于非重力物理学(例如,核物质状态方程)。
Using Effective Field Theory (EFT) methods, we compute the effects of horizon dissipation on the gravitational interactions of relativistic binary black hole systems. We assume that the dynamics is perturbative, i.e it admits an expansion in powers of Newton's constant (post-Minkowskian, or PM, approximation). As applications, we compute corrections to the scattering angle in a black hole collision due to dissipative effects to leading PM order, as well as the post-Newtonian (PN) corrections to the equations of motion of binary black holes in non-relativistic orbits, which represents the leading order finite size effect in the equations of motion. The methods developed here are also applicable to the case of more general compact objects, eg. neutron stars, where the magnitude of the dissipative effects depends on non-gravitational physics (e.g, the equation of state for nuclear matter).
