论文摘要
我们检查了一个缓慢旋转的中子恒星对非landender积聚托里的振荡的四极力矩的影响。我们应用先前开发的方法来对hartle-thorne几何形状的特定情况下的圆环的径向表环模式的频率进行分析计算。我们在这里提出了初步结果，并在先前获得标准和线性化的Kerr几何形状的频率和先前获得的频率之间进行了简要比较。最后，我们很快讨论了在低质量X射线二进制中观察到的高频准周期振荡模型的后果。
We examine the influence of the quadrupole moment of a slowly rotating neutron star on the oscillations of non-slender accretion tori. We apply previously developed methods to perform analytical calculations of frequencies of the radial epicyclic mode of a torus in the specific case of the Hartle-Thorne geometry. We present here our preliminary results and provide a brief comparison between the calculated frequencies and the frequencies previously obtained assuming both standard and linearized Kerr geometry. Finally, we shortly discuss the consequences for models of high-frequency quasi-periodic oscillations observed in low-mass X-ray binaries.
