Modulation of X-ray flux by obscuration of neutron star boundary layer
Gabriel Török, Kateřina Klimovičová, Debora Lančová +6
The quasi-periodic oscillations (QPOs) observed in the X-ray variability of both black hole (BH) and neutron star (NS) systems provide a tool for probing strong gravity and dense m…
Orbital Motion in Spacetimes Influenced by the Presence of Scalar and Electromagnetic Fields
J. Horák, T. Tahamtan, T. Hale +3
The study investigates orbital motion of test particles near compact objects described by solutions involving massless scalar fields, electromagnetic fields, and nonlinear electrod…
Oscillations of non-slender tori in the external Hartle-Thorne geometry
Monika Matuszková, Kateřina Klimovičová, Gabriela Urbancová +3
We examine the influence of the quadrupole moment of a slowly rotating neutron star on the oscillations of non-slender accretion tori. We apply previously developed methods to perf…
Observational properties of puffy disks: radiative GRMHD spectra of mildly sub-Eddington accretion
Maciek Wielgus, Debora Lancova, Odele Straub +7
Numerical general relativistic radiative magnetohydrodynamic simulations of accretion disks around a stellar mass black hole with a luminosity above 0.5 of the Eddington value reve…
Models of high-frequency quasi-periodic oscillations and black hole spin estimates in Galactic microquasars
Andrea Kotrlová, Eva Šrámková, Gabriel Török +6
We explore the influence of non-geodesic pressure forces that are present in an accretion disk on the frequencies of its axisymmetric and non-axisymmetric epicyclic oscillation mod…
Timescale of twin-peak quasi-periodic oscillations and mass of accreting neutron stars
Gabriel Török, Kateřina Goluchová, Eva Šrámková +2
Einstein's general relativity predicts that orbital motion of accreted gas approaching a neutron star (NS) in a NS low-mass X-ray binary (LMXB) system occurs on a time scale propor…
