Low-frequency quasi-periodic oscillations spectra and Lense–Thirring precession
Low-frequency quasi-periodic oscillations spectra and Lense–Thirring precession
We show that the low frequency QPO seen in the power density spectra of black hole binaries (and neutron stars) can be explained by Lense-Thirring precession. This has been proposed many times in the past, and simple, single radius models can qualitatively match the observed increase in QPO frequency by …
