摘要:

本文研究了类星体B31633 +382中致密喷流的运动。通过对22 GHz三个分量(B1、B2和B3)14个历元的VLBI观测分析,发现了两种不同的分量分类可能性。因此,可以采用两种相应的运动学模型来解释构件的演化轨迹。一个是直线运动,而另一个是螺旋模型。未来的观测需要提供新的运动学约束,这些组件在这个源的运动。

英文摘要:

We present a study of the motion of compact jet components in quasar B3 1633+382. Through analyzing 14 epochs of VLBI observations of three components (B1, B2, and B3) at 22 GHz, we find two different possibilities of component classification. Thus two corresponding kinematical models can be adopted to explain the evolutionary track of components. One is a linear motion, while another is a helical model. Future observations are needed to provide new kinematical constraints for the motion of these components in this source.
