摘要
我们总结了LSR相对于反中心碳星运动的测量结果。新的径向速度与现有的K波段光度法相结合，研究了平均速度和色散作为距离的函数。碳星相对于LSR的平均速度为6 km s−1，色散为23 km s−1，且随距离的变化趋势不明显。我们认为碳星数据与Blitz和Spergel(1991)提出的模型并不一致，而更倾向于Kuijken(1991)的模型。
Examining motion of the LSR using anticenter carbon stars
We summarize results of a measurement of the motion of the LSR with respect to anticenter carbon stars. New radial velocities were combined with existing K‐band photometry to examine the velocity mean and dispersion as a function of distance. The mean velocity of the carbon stars relative to the LSR is 6 km s−1 with a dispersion of 23 km s−1, and no trends with distance are evident. We conclude that the carbon star data are not consistent with the model proposed by Blitz and Spergel (1991), and tend to agree with the model of Kuijken (1991) more closely.
