On the distribution of frequency ratios of kHz QPOs
Martin Boutelier, Didier Barret, Yongfeng Lin +1
The width (W), root mean squared amplitude (Rs) of lower and upper kHz quasi-periodic oscillations (QPOs) from accreting neutron stars vary with frequency. Similarly, the QPO frequ…

Internal resonance in non-linear disk oscillations and the amplitude evolution of neutron star kilohertz QPOs
J. Horak, M. A. Abramowicz, W. Kluzniak +2
We explore some properties of twin kilohertz quasiperiodic oscillations (QPOs) in a simple toy-model consisting of two oscillation modes coupled by a general nonlinear force. We ex…
