| 英文摘要 | During the period 1966.5-2006.2 the 15 GHz and 8 GHz light curves of 3C 454.3 (z = 0.859) show a quasi-periodicity of similar to 12.8 yr (similar to 6.9 yr in the rest frame of the source) with a double-bump structure. This periodic behaviour is interpreted in terms of a rotating double-jet model in which the two jets are created from the black holes of a binary system and rotating with the period of the orbital motion. The periodic variations in the radio fluxes of 3C 454.3 are suggested to be mainly due to the lighthouse effects (or the variation in Doppler boosting) of the precessing jets caused by the orbital motion. In addition, variations in the rate of mass accreting onto the black holes may be also involved. |
