Scientific paper

The innermost parts of accretion discs around black holes are subject to strong gravity and may be the realm where quasi periodic oscillations (QPOs) originate. Several X-ray binaries with known mass estimates show at high frequencies a stable QPO pair in a 3:2 ratio. We found that non-slender fluid tori around Kerr black holes oscillate for any given spin parameter a with lower epicyclic frequencies than free particles. These pressure corrected epicyclic frequencies of non-slender tori in Kerr metric were used to model the upper and lower QPO as a combination of radial and vertical epicyclic frequency with the Keplerian orbital frequency to estimate the black hole spin.
