Epicyclic Oscillations around Simpson-Visser Regular Black Holes and Wormholes
Zdeněk Stuchlík, Jaroslav Vrba
We study epicyclic oscillatory motion along circular geodesics of the Simpson--Visser meta-geometry describing in a unique way regular black-bounce black holes and reflection-symme…
Dynamical stability of the modified Tolman VII solution
Camilo Posada, Jan Hladík, Zdeněk Stuchlík
Studies of neutron stars are at their peak after the multi-messenger observation of the binary merger event GW170817, which strongly constraints the stellar parameters like tidal d…
Polytropic spheres modelling dark matter halos of dwarf galaxies
Jan Novotný, Zdeněk Stuchlík, Jan Hladík
Dwarf galaxies and their dark matter (DM) halos have the velocity curves of a different character than those in large galaxies. They are modelled by a simple pseudo iso-thermal mod…
Charged particle and epicyclic motions around Einstein-Gauss-Bonnet black hole immersed in an external magnetic field
Sanjar Shaymatov, Jaroslav Vrba, Daniele Malafarina +2
We investigate particle motion in the vicinity of a Einstein-Gauss-Bonnet (EGB) black hole immersed in external asymptotically uniform magnetic field. It is well known that ma…
Radial instability of trapping polytropic spheres
Jan Hladík, Camilo Posada, Zdeněk Stuchlík
We complete the stability study of general relativistic spherically symmetric polytropic perfect fluid spheres, concentrating attention to the newly discovered polytropes containin…
Quasinormal modes of magnetized black hole
Bobur Turimov, Bobir Toshmatov, Bobomurat Ahmedov +1
We investigate charged, massive scalar field around static, spherically symmetric black hole immersed into an external asymptotically uniform magnetic field . It is shown that f…
