论文摘要
在表现出自发标识的重力理论中，天体物理对象与它们的一般相对论对应物相同，直到它们达到紧凑或曲率的一定阈值。除了这个阈值之外，他们还获得了非平凡的标量配置，这也会影响其结构。标量的发作仅由围绕一般相对性解决方案的线性扰动的术语控制。这些术语的完整集已确定为广义标量调整理论。在此结果中，我们研究了广义标量调整理论中标量的开始，并根据贡献耦合常数和紧凑型对象的性质确定相关阈值。
In gravity theories that exhibit spontaneous scalarization, astrophysical objects are identical to their general relativistic counterpart until they reach a certain threshold in compactness or curvature. Beyond this threshold, they acquire a non-trivial scalar configuration, which also affects their structure. The onset of scalarization is controlled only by terms that contribute to linear perturbation around solutions of general relativity. The complete set of these terms has been identified for generalized scalar-tensor theories. Stepping on this result, we study the onset on scalarization in generalized scalar-tensor theories and determine the relevant thresholds in terms of the contributing coupling constants and the properties of the compact object.
