类星体3C 273 X射线波段周期特性分析
Analysis of the Variability Periodicities of Quasar 3C 273 in the X-ray Band
摘要
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℃. 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.关键词
