天鹰座X-1能谱和千赫兹准周期振荡频率的相关

Correlation between the Kilohertz Quasi-Periodic Oscillation and Energy Spectrum of Aql X-1

通过分析1997年2月27日和3月1日对天鹰座X-1的两次空间数据观测．发现千赫兹QPO频率同X射线能诺有一定相关，其行为类似于另一个X射线暂现源4U1608-52，讨论了分析结果对了解吸积及QPO产生过程的意义．

Worn an analysis of the observed data of the X-ray transient Aquila X-1 on 1997 February 27 and March 1, we find that there exists some correlation between the frequency of kilohertz quasi-periodic oscillations and the shape of X-ray spectrum, similar to the case of the X-ray transient 4U 1608-52. Implications of our results for the accretion and QPO production process are discussed.
