Periodic orbits and gravitational wave signatures from magnetic dipoles around magnetized Kerr black holes
Shokhzod Jumaniyozov, Javlon Rayimbaev, Chengxun Yuan +3
We study periodic orbits and the associated gravitational radiation of a magnetized (uncharged) test particle carrying a magnetic dipole moment with coupling constant beta, moving…
Gravitational perturbations of a regular T-duality inspired black hole: Quasinormal modes, excitation factors, and time-domain evolution
Bekir Can Lütfüoğlu, Mardon Abdullaev, Javlon Rayimbaev +2
We study axial gravitational perturbations of the neutral regular black hole generated by a non-local, T-duality-inspired zero-point length and the associated gravitational self-en…
Tidal Deformability of Neutron Stars in Bumblebee Gravity: Probing Lorentz Symmetry Breaking with Gravitational Waves
Ayan Banerjee, sherzod Sayfiyev, Muhtarama Radjapbaeva +3
We investigate the tidal properties of static neutron stars in the Neves--Gardim branch of bumblebee gravity, a vector--tensor theory in which a nonzero vacuum expectation value of…
Role of spin-curvature and magnetic interactions on circular orbits of particles with magnetic monopole around Bardeen black holes
Shokhzod Jumaniyozov, Javlon Rayimbaev, Yuan Chengxun +3
We investigate the dynamics of magnetically charged spinning test particles in the spacetime of the Bardeen regular black hole, sourced by nonlinear electrodynamics and featuring a…
Corrected thermodynamics and radiation predictions of modified black bounce compact objects
Shokhzod Jumaniyozov, Javlon Rayimbaev, Yassine Sekhmani +3
We study the thermodynamic properties and radiation characteristics of a regular compact object obtained by applying the Simpson-Visser (SV) regularisation to the Schwarzschild mod…
