一般DHOST理论中的规则黑洞和类引力粒子解

Regular black holes and gravitational particle-like solutions in generic DHOST theories

Olaf Baake, Christos Charmousis, Mokhtar Hassaine, Miguel San Juan

摘要:

利用高阶标量张量(DHOST)理论,构造了正则、渐近平坦的黑洞.这些解依赖于一个质量积分常数,允许一个光滑核的选择规则性,一般有一个内部和外部事件视界。特别是,低于一定的质量阈值,我们发现大量的,无视界的,粒子般的解决方案。我们扫描了从弱引力到强引力的可能观测信号,并研究了我们正则解的热力学,在可能的情况下,将它们与广义相对论黑洞及其热力学定律进行比较。

英文摘要:

We construct regular, asymptotically flat black holes of higher order scalar tensor (DHOST) theories, which are obtained by making use of a generalized Kerr-Schild solution generating method. The solutions depend on a mass integration constant, admit a smooth core of chosen regularity, and generically have an inner and outer event horizon. In particular, below a certain mass threshold, we find massive, horizonless, particle-like solutions. We scan through possible observational signatures ranging from weak to strong gravity and study the thermodynamics of our regular solutions, comparing them, when possible, to General Relativity black holes and their thermodynamic laws.
