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…
Interpreting black hole QPOs
Marek A. Abramowicz, Wlodzimierz Kluzniak
In all the microquasars with two hHz QPOs, the ratio of the frequencies is 3:2, supporting our suggestion that a non-linear resonance between two modes of oscillation in the accret…
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…
