N2  - We examine the influence of the quadrupole moment of a slowly rotating neutronstar on the oscillations of non-slender accretion tori. We apply previously developedmethods to perform analytical calculations of frequencies of the radial epicyclicmode of a torus in the specific case of the Hartle-Thorne geometry. We presenthere our preliminary results and provide a brief comparison between the calculated frequencies and the frequencies previously obtained assuming both standard and lin-earized Kerr geometry. Finally, we shortly discuss the consequences for models of high-frequency quasi-periodic oscillations observed in low-mass X-ray binaries.
