Continued fraction method for high overtone quasinormal modes in effective potentials with discontinuity
Guan-Ru Li, Jodin C. Morey, Wei-Liang Qian +4
In this study, we extend Leaver's continued fraction method to evaluate black hole quasinormal modes (QNMs) in systems where the effective potential exhibits a discontinuity. Besid…

Echoes of bimodal axial gravitational perturbations in a uniform-density star in Einstein-Ãther gravity
Kai Lin, Wei-Liang Qian, Alan B. Pavan +2
This paper studies axial gravitational perturbations of a uniform-density star in scalar-Einstein-Ãther theory. By applying the Israel junction conditions explicitly in the presen…
