摘要:

Blazar OJ 287是最有希望的(也是唯一的)河外双星黑洞系统在引力辐射反应作用下发生螺旋运动的例子。目前,虽然不可能直接观测到双星的组成部分,但可以观测到从主黑洞发出的喷流。我们认为次级黑洞的轨道运动反映在喷流的摆动中,并证明这种摆动与轨道位置有关。Agudo等人(2012)报告的喷流的不稳定摆动通过考虑系统的二元性质进行了分析,我们发现喷流摆动的不稳定分量非常小。

英文摘要:

The blazar OJ287 is the most promising (and the only) case for an extragalactic binary black hole system inspiralling under the action of gravitational radiation reaction. At present, though it is not possible to directly observe the binary components, it is possible to observe the jet emanating form the primary black hole. We argue that the orbital motion of the secondary black hole is reflected in the wobble of the jet and demonstrate that the wobble is orbital position dependent. The erratic wobble of the jet, reported in Agudo et al. (2012), is analyzed by taking into account the binary nature of the system and we find that the erratic component of jet wobble is very small.
