摘要
我们在利用上海和SHEVE组成的VLBI网做南天区5GHzVLBI普查的过程中,对致密射电源0106+013的视超光速运动作了进一步的研究.结果表明:(1)分量1最有可能是核;(2)原视超光速喷流分量仍以0.2mas/yr的自行速度向外运动;(3)发现一个新分量的爆发,新分量也是视超光速的,自行速度为0.18mas/yr;(4)喷流在大约5mas处有较明显的弯曲,然后趋于与VLA喷流的方向一致.
We observed 0106+013 with a VLBI array of SHEVE plus Shanghai at 5 GHz. The results show that (1) the component 1 is most likely the core, (2) the original superluminal component is still moving outwards at a speed of 0.2 mas/yr, (3) a new component emerging from the core is moving outwards at a speed of 0.18 mas/yr, and (4) the jet bends within 5 mas of the core and then extends along the VLA jet.
