论文摘要
4U 1728-34的X射线光谱中的三个平均光曲线包含三合一的准周期振荡：两个kHz，一个鞋面和一个下部和一个低频。在当前的工作中，假设三合会同时出现并且随着相对论进动模型的应用，获得了环礁源4U 1728-34中中子星的质量和旋转。还测试了质量和自旋三个独立估计的一致性。根据获得的结果，研究的中子恒星具有相对较高的质量和中等自旋。
Three of the averaged light curves from the X-ray spectrum of 4U 1728-34 contain triads of quasi-periodic oscillations: two kHz, an upper and a lower one, and one low-frequency. In the present work, with the assumption that the triads occur simultaneously and with the application of the relativistic precession model the mass and the spin of the neutron star in the atoll source 4U 1728-34 is obtained. The consistency of the three independent estimates of the mass and the spin is also tested. According to the obtained results, the studied neutron star has relatively high mass and moderate spin.
