Epicyclic oscillations of fluid bodies Paper II. Strong gravity
Marek A. Abramowicz, Omer M. Blaes, Jiri Horak +2
Fluids in external gravity may oscillate with frequencies characteristic of the epicyclic motions of test particles. We explicitly demonstrate that global oscillations of a slender…
High frequency QPOs: nonlinear oscillations in strong gravity
Wlodek Kluzniak
Some of the more promising ideas about the origin of the high frequency variability (kHz QPOs) in the observed X-ray emissions of low-mass X-ray binaries are contrasted with less p…
The correlations and anticorrelations in QPO data
M. A. Abramowicz, D. Barret, M. Bursa +4
Double peak kHz QPO frequencies in neutron star sources varies in time by a factor of hundreds Hz while in microquasar sources the frequencies are fixed and located at the line ν_2…
QPOs in Cataclysmic Variables and in X-ray Binaries
Wlodek Kluzniak, Jean-Pierre Lasota, Marek A. Abramowicz +1
Recent observations, reported by Warner and Woudt, of Dwarf Nova Oscillations (DNOs) exhibiting frequency drift, period doubling, and 1:2:3 harmonic structure, can be understood as…
