视超光速源0106+013的观测研究

The Superluminal Source 0106+013

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.
