Lense-Thirring precession of neutron-star accretion flows: Relativistic versus classical precession
Gabriel Török, Martin Urbanec, Monika Matuszková +5
The vertical (Lense-Thirring) precession of the innermost accretion flows has been discussed as a sensitive indicator of the rotational properties of neutron stars (NSs) and their…

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…

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…
