Gravitational-Wave Echoes from Layered Compact Objects: A Double-Shell Model
Qi Su, Ding-Fang Zeng
Layering is a ubiquitous feature of astrophysical objects. Motivated by the fact that physical black holes retain the layered structure of their progenitor stars when viewed in the…
Gravitational-Bumblebee perturbations: Exact decoupling and isospectrality
Hui-Fa Liu, Wentao Liu, Yu-Xiao Liu +2
In this paper, we present the exact decoupling of the full metric and bumblebee field perturbations in a Schwarzschild-like background. The coupled system reduces to four decoupled…
Merger Dynamics of N+N Co-planar Particles in Newton Gravitation
Qi Su, Baicheng Zhang, Ding-Fang Zeng
We model the inspiral and merger dynamics of two co-planar rings in Newtonian mechanics with GR motivated corrections and illustrate their similarity with those of black hole binar…
Quasinormal modes of Reissner-Nordström-AdS black holes under physical field-vanishing boundary conditions
Hui-Fa Liu, Qi Su, Ding-fang Zeng
Boundary conditions play a key role in determining the perturbation behavior of a black hole. Motivated by two guiding principles for single-field perturbations -- the non-deformat…
