论文摘要
暗物质或被困在天体内物体内部的新颗粒的亚摘要可以显着改变其宏观特性。我们通过使用通用框架来解决tolman-oppenheimer-volkoff（TOV）方程来研究天体对象上的新物理印迹，以最多两种流体。我们测试了新颗粒人群对天体物体的影响，包括对自我相互作用大小的敏感性，新的颗粒质量和净种群质量。将我们的设置应用于中子星和玻色子恒星，我们发现了这些参数的丰富现象学，包括创建扩展的大气。这些大气可以通过对潮汐爱数字的影响来检测，可以在即将进行的重力波实验（例如晚期Ligo，Einstein望远镜和Lisa）中进行测量。我们将计算框架作为公开代码发布，从而使TOV方程在小说和混合的天体对象中的任意新物理模型中始终可以解决。
A sub-fraction of dark matter or new particles trapped inside celestial objects can significantly alter their macroscopic properties. We investigate the new physics imprint on celestial objects by using a generic framework to solve the Tolman-Oppenheimer-Volkoff (TOV) equations for up to two fluids. We test the impact of populations of new particles on celestial objects, including the sensitivity to self-interaction sizes, new particle mass, and net population mass. Applying our setup to neutron stars and boson stars, we find rich phenomenology for a range of these parameters, including the creation of extended atmospheres. These atmospheres are detectable by their impact on the tidal love number, which can be measured at upcoming gravitational wave experiments such as Advanced LIGO, the Einstein Telescope, and LISA. We release our calculation framework as a publicly available code, allowing the TOV equations to be generically solved for arbitrary new physics models in novel and admixed celestial objects.
