Unveiling hidden variability components in accreting X-ray binaries using both the Fourier power and cross spectra
Mariano Mendez, Valentina Peirano, Federico Garcia +3
We present a novel method for measuring the lags of (weak) variability components in neutron-star and black-hole low-mass X-ray binaries (LMXBs). For this we assume that the power…

Lags of the KiloHertz Quasi-Periodic Oscillations in the transient source XTE J1701462
Valentina Peirano, Mariano Méndez
We analysed 14 observations with kilohertz quasi-periodic oscillations (kHz QPOs) of the neutron star X-ray binary XTE J1701462, the first source to show a clear transition betw…

Kilohertz quasi-periodic oscillations in neutron-star X-ray binaries: Flattening of the lag spectrum with increasing luminosity
Valentina Peirano, Mariano Méndez
We study the energy-dependent time lags and rms fractional amplitude of the kilohertz quasi-periodic oscillations (kHz QPOs) of a group of neutron-star low mass X-ray binaries (LMX…
