| 摘 要： | 收集了Ariel V ssI、GINGA、EXOSAT及RXTEX卫星在X射线波段（2-10keV）的观测数据点1059个,获得了类星体3C273从1976年至2008年的历史光变曲线。利用Jurkevich方法及DCF方法计算并分析了类星体3C273的光变周期,结果表明,3C273在X射线波段的光变周期为14.45±0.15年。此外,针对这一光变周期结果,用双黑洞模型对其中心黑洞质量进行了估算和讨论。

| Abstract: | In this paper,we have colleted a total of 1059 observational datapoints of quasar 3C 273 from Ariel V ssI,GINGA,EXOSAT and RXTEX in the X-ray band(2-10keV),and constructed its historical light curve from 1976 to 2008,and also used the Jurkevich method and the DCF method to calculate and analyze its variability periodicities,the resuls indicate that its long-term of variation is 14.45±0.15 years in the X-ray band.In addition,we used this period of 3C 273 to estimate and discuss its central black hole mass in terms of the theory of binary black hole model. |
