论文摘要
我们回忆起了其基本性质在一般相对论中的基本特性之后，以替代性重力来解决中子星和黑洞。在很多有趣的替代性重力中，我们着重于一组有趣的标量调整理论。我们讨论了自发标量的现象，这是对中子星和黑洞引起的曲率引起的物质。与其他相关的物理属性一起，我们解决了这些紧凑对象的准正常模式。特别是，我们考虑中子星的\ textit {普遍关系}在很大程度上减少了对状态方程的依赖，我们简要介绍了黑洞的阴影。
We address neutron stars and black holes in alternative gravities, after recalling their basic properties in General Relativity. Among the plethora of interesting alternative gravities we here focus on an interesting set of scalar-tensor theories. We discuss the phenomenon of spontaneous scalarization, that is matter induced for neutron stars and curvature induced for black holes. Along with other relevant physical properties, we address the quasi-normal modes of these compact objects. In particular, we consider \textit{universal relations} of neutron stars to largely reduce the dependence on the equation of state, and we briefly address the shadow of black holes.
