Misalignment of the Lense-Thirring precession by an accretion torque
D. A. Bollimpalli, J. Horák, W. Kluźniak +1
Orbiting matter misaligned with a spinning black hole undergoes Lense-Thirring precession, due to the frame-dragging effect. This phenomenon is particularly relevant for type-C QPO…
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…
Investigating the consistency of the shape and flux of X-ray reflection spectra in the hard state with an accretion disk reaching close to the black hole
Sudeb Ranjan Datta, Michal Dovčiak, Michal Bursa +3
The observed spectra from black hole (BH) X-ray binaries (XRBs) typically consist of two primary components: multitemperature blackbody (BB) originating from the accretion disk in…
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…
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…
