Polish Doughnuts around Scalarized Kerr Black Holes
Matheus C. Teodoro, Lucas G. Collodel, Daniela Doneva +3
In this work we aim to investigate non-mainstream thick tori configurations around Kerr Black Holes with Scalar Hair (KBHsSH). For that goal, we provide a first approach using cons…
Quasi-periodic Oscillations in Rotating Ellis Wormhole Spacetimes
Efthimia Deligianni, Burkhard Kleihaus, Jutta Kunz +2
We analyze the properties of the circular orbits for massive particles in the equatorial plane of symmetric rotating Ellis wormholes. In particular, we obtain the orbital frequenci…
Image of the thin accretion disk around compact objects in the Einstein-Gauss-Bonnet gravity
Galin Gyulchev, Petya Nedkova, Tsvetan Vetsov +1
We study the optical appearance of a thin accretion disk around compact objects within the Einstein-Gauss-Bonnet gravity. Considering static spherically symmetric black holes and n…
Quasi-periodic oscillations from the accretion disk around rotating traversable wormholes
Efthimia Deligianni, Jutta Kunz, Petya Nedkova +2
We study the quasi-periodic oscillations from the accretion disk around rotating traversable wormholes by means of the resonance models. We investigate the linear stability of the…
Polar quasinormal modes of the scalarized Einstein-Gauss-Bonnet black holes
Jose Luis Blázquez-Salcedo, Daniela D. Doneva, Sarah Kahlen +3
We study the polar quasinormal modes of spontaneously scalarized black holes in Einstein-Gauss-Bonnet theory. In previous works we showed that a set of nodeless solutions of the fu…
Observational signatures of strongly naked singularities: image of the thin accretion disk
Galin Gyulchev, Jutta Kunz, Petya Nedkova +2
We study the optical appearance of a thin accretion disk around the strongly naked static Janis-Newman-Winicour singularity. The solution does not possess a photon sphere, which re…
