该研究探讨替代引力理论中的黑洞，聚焦标量-张量理论，指出其黑洞解与广义相对论差异显著，其特征可用于约束理论耦合参数。
AI 中文摘要
黑洞凭借其极强的引力场，为广义相对论之外的引力理论提供了重要的检验场。在众多已提出的替代理论中，近期大量研究聚焦于标量-张量理论，该理论中标量场与高阶曲率项存在耦合。这类理论中产生的黑洞解与广义相对论的史瓦西、克尔解存在显著差异。此类黑洞的特征性质包括不稳定性、阴影以及引力波谱，这些特性可用于约束 underlying 理论的耦合参数。
英文摘要
Black holes, with their strong gravitational fields, provide an important testing ground for theories of gravity beyond General Relativity. Among the many proposed alternatives, considerable recent work has focused on scalar-tensor theories in which a scalar field couples to higher-curvature terms. The black hole solutions that arise in such theories can differ significantly from the Schwarzschild and Kerr solutions of General Relativity. Characteristic properties of these black holes include instabilities, shadows, and gravitational wave spectra, which can be used to constrain the couplings of the underlying theories.
