| 英文摘要 | Three deep flux minima with nearly the same time-scales and intervals have been observed for the blazar PKS 1510-089 in the past few years. It has been proposed that there is a binary black hole system at the nucleus of this object, and a new minimum was predicted to occur in 2002 March. We monitored this source with a 60/90 cm Schmidt telescope from 2002 February to April. In combination with the data obtained by Xie et al. in the same period, for the 2002 minimum we present a nearly symmetric light curve, which would be required by an eclipsing model of a binary black hole system. We also constrain the time-scale of the minimum to be 35 min, which is more consistent with the time-scales (similar to 42 min) of the three previous minima than is the 89 min time-scale given by Xie et al. The wiggling milliarcsecond radio jet observed in this object is taken as further evidence for the binary black hole system. The 'coupling' of the periodicity in the light curve and the helicity in the radio jet is discussed for blazars in the framework of a binary black hole system. |
