The orbital resonance model for twin peak kHz QPOs
Marek A. Abramowicz, Wlodek Kluzniak, Zdenek Stuchlik +1
Many Galactic black hole and neutron star sources in low X-ray mass binaries show QPOs (quasi periodic oscillations) in their observed X-ray fluxes, i.e. peaks in the Fourier varia…
The Hartle-Thorne circular geodesics
M. A. Abramowicz, G. J. E. Almergren, W. Kluzniak +1
The Hartle-Thorne metric is an exact solution of vacuum Einstein field equations that describes the exterior of any slowly and rigidly rotating, stationary and axially symmetric bo…
Millisecond oscillators in accreting neutron stars and black holes
W. Kluzniak, M. Abramowicz
Millisecond variability detected in low-mass X-ray binaries (LMXBs) probably reflects motions of accreting fluid in the strong-field gravity of neutron stars or neutron stars. Para…
An unusually low mass of some "neutron" stars?
D. Gondek-Rosinska, W. Kluzniak, N. Stergioulas
The X-ray emission of RXJ1856.5-3754 has been found to coincide to unprecedented accuracy with that of a blackbody, of radius 5.8+-0.9 km for the measured parallax distance of 140…
Population synthesis of compact objects: neutron stars, strange (quark) stars and black holes
Krzysztof Belczynski, Tomasz Bulik, Wlodzimierz Kluzniak
We compute and present the distribution in mass of single and binary neutron stars, strange stars, and black holes. The calculations were performed using a stellar population synth…
Binary coalescence of a strange star with a black hole: Newtonian results
William H. Lee, Wlodzimierz Kluzniak, Jon Nix
We present Newtonian three-dimensional hydrodynamical simulations of the merger of quark stars with black holes. The initial conditions correspond to non-spinning stars in Kepleria…
