THis project targets the modeling of compact objects in the framework of Einstein's relativity, study the dynamics of these objects -- either single objects or binaries -- and their emission of gravitational waves detectable by the LIGO or LISA detectors. More specifically, we aim to use the GRChombo code to model compact stars made up of fundamental fields and black holes surrounded by fundamental fields. Key goals are the determination of the stability of so-called hairy black holes and binary systems composed of boson stars, black holes and/or hairy black holes. The reulsting gravitational wave signals are to be compared with those emitted by vacuum black-hole binaries to search for signatures that would enable us to observationally discriminate between the different sources.

这个项目的目标是在爱因斯坦相对论的框架内对紧凑物体进行建模，研究这些物体的动力学-无论是单个物体还是二进制物体-以及它们发射的引力波可以被LIGO或丽莎探测器探测到。更具体地说，我们的目标是使用GRChombo代码来模拟由基本场和被基本场包围的黑洞组成的致密恒星。主要目标是确定所谓的毛状黑洞和由玻色子星、黑洞和/或毛状黑洞组成的双星系统的稳定性。我们将把这些强烈的引力波信号与真空黑洞双星发出的引力波信号进行比较，以寻找能够使我们在观测上区分不同来源的特征。
