利用美国甚长基线阵,在5GHz和8GHz波段观测致密陡谱源(CSS)1150+497,获得的5GHz总流量图显示1150+497有单边喷流结构。在5GHz波段该源的西南方向探测到3个亮结,在东北方向探测到一个亮结。在8GH:波段该源的西南方向探测到2个亮结。在5GHz波段,根据子源A和E自1982~2001年间3个时段的VLBI观测成图结果,拟合出它们的分离速度为0.478±0.007mas/year。
The compact steep-spectrum (CSS) source 1150+ 497 was observed with the Very Long Baseline Array (VLBA) at 5GHz and 8GHz bands. The obtained total intensity image at 5GHz shows that 1150 + 497 has a bright one-side jet. At 5GHz, there are three knots in the southwest and one knot in the northeast. At 8GHz, two knots can be modeled in the southwest. Analyzing images at 5 GHz band in 3 epochs from 1982 to 2001 , an estimate of separation velocity 0.478 ± 0.007 mas/year is derived as the relative motions of components A and E.
