论文摘要
当它显示出低频准周期振荡(QPOS)时,使用GRS 1915+105的Insight-HXMT观察结果,我们测量了QPO频率的演变以及磁盘内部半径和质量积聚率。我们发现QPO频率和质量积聚率之间存在紧密的正相关。我们的结果将先前与Astrosat的作品的发现扩展到具有独立工具和观察结果的更大范围。将GRS 1915+105的QPO频率视为截短磁盘的相对论动态频率,我们能够确认GRS 1915+105中黑洞的高旋转性质。我们还解决了我们发现未来测试一般相对论的潜力。
Using the Insight-HXMT observations of GRS 1915+105 when it exhibits low frequency quasi-periodic oscillations (QPOs), we measure the evolution of the QPO frequency along with disk inner radius and mass accretion rate. We find a tight positive correlation between the QPO frequency and mass accretion rate. Our results extend the finding of previous work with AstroSat to a larger range of accretion rate with independent instruments and observations. Treating the QPO frequency of GRS 1915+105 as the relativistic dynamic frequency of a truncated disk, we are able to confirm the high spin nature of the black hole in GRS 1915+105. We also address the potential of our finding to test general relativity in the future.
