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…

Wave-fronts of gravitational waves partially trapped in ultra-compact stars
Marek Abramowicz, Jiří Horák, Kateřina Klimovičová
We dedicate this work to Dr Omer Blaes, professor of physics at UCSB, on the occasion of his sixtieth birthday. We have been collaborating now and then with Dr. Blaes on problems i…
