Three-dimensional general relativistic Poynting-Robertson effect II: Radiation field from a rigidly rotating spherical source
Pavel Bakala, Vittorio De Falco, Emmanuele Battista +4
We investigate the three-dimensional, general relativistic Poynting-Robertson effect in the case of rigidly rotating spherical source which emits radiation radially in the local co…
Constraining models of twin peak quasi-periodic oscillations with realistic neutron star equations of state
Gabriel Török, Kateřina Goluchová, Martin Urbanec +8
Twin-peak quasi-periodic oscillations (QPOs) are observed in the X-ray power-density spectra of several accreting low-mass neutron star (NS) binaries. In our previous work we have…
Hořava's quantum gravity illustrated by embedding diagrams of the Kehagias-Sfetsos spacetimes
Kateřina Goluchová, Konrad Kulczycki, Ronaldo S. S. Vieira +3
Possible astrophysical consequences of the Hořava quantum gravity theory have been recently studied by several authors. They usually employ the Kehagias-Sfetsos (KS) spacetime whic…
Equations of state in the Hartle-Thorne model of neutron stars selecting acceptable variants of the resonant switch model of twin HF QPOs in the atoll source 4U 1636-53
Zdenek Stuchlik, Martin Urbanec, Andrea Kotrlova +2
The Resonant Switch (RS) model of twin high-frequency quasi-periodic oscillations (HF QPOs) observed in neutron star binary systems, based on switch of the twin oscillations at a r…
Simulations of flux variability of oscillating accretion fluid tori around Kerr black holes
Pavel Bakala, Kateřina Goluchová, Eva Šrámková +4
High frequency quasi-periodic oscillations (HF QPOs) are observed in the X-ray power-density spectra (PDS) of several microquasars and low mass X-ray binaries. Many proposed QPO mo…
Mass-angular-momentum relations implied by models of twin peak quasi-periodic oscillations
Gabriel Torok, Pavel Bakala, Eva Sramkova +3
Twin peak quasi-periodic oscillations (QPOs) appear in the X-ray power-density spectra of several accreting low-mass neutron star (NS) binaries. Observations of the peculiar Z-sour…
Restrictions to neutron star properties based on twin-peak quasi-periodic oscillations
Gabriel Torok, Pavel Bakala, Eva Sramkova +3
We consider twin-peak quasi-periodic oscillations observed in the accreting low-mass neutron star binaries and explore restrictions to central compact object properties that are im…
