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…

The three-dimensional general relativistic Poynting-Robertson effect I: radial radiation field
Vittorio De Falco, Pavel Bakala, Emmanuele Battista +3
In this paper we investigate the three-dimensional (3D) motion of a test particle in a stationary, axially symmetric spacetime around a central compact object, under the influence…
