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…

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…

On one-parametric formula relating the frequencies of twin-peak quasi-periodic oscillations

Gabriel Török, Kateřina Goluchová, Eva Šrámková +3

Twin-peak quasi-periodic oscillations (QPOs) are observed in several low-mass X-ray binary systems containing neutron stars (NSs). Timing analysis of X-ray fluxes of more than doze…
