Exact radial stability threshold for a Minkowski-Schwarzschild thin shell
Anuar Idrissov
We study the stability of a thin shell of ordinary matter that separates a flat interior from a Schwarzschild exterior, which is the simplest model of a subluminal warp drive. The…
Naked Singularities and Black Hole Thermodynamics from Shadows and Photon Rings in the Quantum Oppenheimer-Snyder Model
Jose Miguel Ladino, Anuar Idrissov, Carlos E. Romero-Figueroa +1
We investigate the optical and thermodynamic properties of quantum Oppenheimer-Snyder (qOS) spacetimes in both the black hole and naked singularity regimes. By analyzing test-parti…
Static Spherically Symmetric Solutions in Nonconservative Unimodular Gravity
Anuar Idrissov, Hernando Quevedo
We study static and spherically symmetric black holes in nonconservative unimodular gravity, where the traceless field equations determine the source of a given geometry only up to…
Observational properties of magnetized quantum Oppenheimer-Snyder black holes
Anuar Idrissov, Hernando Quevedo
We consider a thin accretion disk around the quantum Oppenheimer-Snyder black hole immersed in an asymptotically uniform magnetic field, together with the gravitational capture of…
Tidal forces in the quantum Oppenheimer--Snyder black hole
Anuar Idrissov, Hernando Quevedo
We investigate the tidal forces experienced by massive particles in radial free fall in the quantum Oppenheimer--Snyder black hole, a loop quantum gravity correction to the Schwarz…
Newtonian Shirokov Effect: Epicyclic Frequency Splitting from Mass Multipoles
Anuar Idrissov, Kuantay Boshkayev, Abylaikhan Tlemissov +1
We analyze small oscillations of nearly circular orbits in an axisymmetric Newtonian potential expanded in mass multipoles, as the classical counterpart of the relativistic Shiroko…
Shirokov and Shapiro Effects in the Hartle-Thorne Spacetime
Anuar Idrissov, Kuantay Boshkayev, Serzhan Momynov +4
We investigate the influence of rotation and quadrupole deformations of astrophysical compact objects on the Shirokov and Shapiro effects within the Hartle-Thorne spacetime, which…
