Axial Gravitational Normal Modes of Uniform Density Star in Anti-de Sitter Spacetime
Kai Lin, Alan B. Pavan, Amilcar Rabelo de Queiroz +1
The article studies the dynamical behavior of axial gravitational perturbations of homogeneous stars in Anti-de Sitter spacetime. Because the radial coordinate transforms into…
Echoes of bimodal axial gravitational perturbations in a uniform-density star in Einstein-Æther gravity
Kai Lin, Wei-Liang Qian, Alan B. Pavan +2
This paper studies axial gravitational perturbations of a uniform-density star in scalar-Einstein-Æther theory. By applying the Israel junction conditions explicitly in the presenc…
New Electrically Charged Black Hole in Higher Derivative Gravity
Kai Lin, A. B. Pavan, G. Flores-Hidalgo +1
In this paper, new electrically charged asymptotically flat black hole solutions are numerically derived in the context of higher derivative gravity. These solutions can be interpr…
Regular Phantom Black Hole and Holography: very high temperature superconductors
Kai Lin, A. B. Pavan, Qiyuan Pan +1
Holographic superconductors containing a non-minimal derivative coupling for scalar field in a regular phantom plane symmetric black hole have been considered. We show that the par…
Exact cosmological solutions of models with an interacting dark sector
A. B. Pavan, Elisa G. M. Ferreira, Sandro M. R. Micheletti +2
In this work we extend the first order formalism for cosmological models that present an interaction between a fermionic and a scalar field. Cosmological exact solutions describing…
An Extensive Search for Overtones in Schwarzschild Black Holes
E. Abdalla, D. Giugno
In this paper we show that with standard methods it is possible to obtain highly precise results for QNMs. In particular, secondary modes are obtained by numerical integration. We…
