论文摘要
在现代的X射线探测和引力波天文学的势头日益增加的现代时代，在强场地制度中对一般相对性的一般相对性的测试变得越来越可行，并且其对探测重力的重要性不能低估。为此，我们研究了两位作者对这种新型的紧凑物体进行静态研究，研究了重力张量量表中缓慢旋转拓扑中子星的特征。我们探讨了惯性的时刻，并验证了这种新的紧凑型对象所知的普遍关系。此外，我们研究了它们最内向的圆形轨道（ISCO）的性质以及由于后者与观测量的链接（例如准周期X射线频谱特征）所暗示的链接所致。
In the modern era of abundant X-ray detections and the increasing momentum of gravitational waves astronomy, tests of General Relativity in strong field regime become increasingly feasible and their importance for probing gravity cannot be understated. To this end, we study the characteristics of slowly rotating topological neutron stars in the tensor-multi-scalar theories of gravity following the static study of this new type of compact objects by two of the authors. We explore the moment of inertia and verify that universal relations known from General Relativity hold for this new class of compact objects. Furthermore, we study the properties of their innermost stable circular orbits (ISCO) and the epicyclic frequencies due to the latter's hinted link to observational quantities such as quasi-periodic X-ray spectrum features.
