NettetWhen the two stars are both moving across our line of sight (neither away from nor toward us), they both have the same radial velocity (that of the pair’s center of mass); hence, the spectral lines of the two stars come together. This is shown in the two bottom illustrations in Figure 18.6. Nettet12. apr. 2016 · The observed fields are located to cover an angular extent of $\sim 17$\arcdeg along the stream, providing an opportunity to investigate a trend in line-of-sight velocities ($V_{\rm los}$) along the stream, which is essential to constrain its orbit and underlying gravitational potential of the Milky Way's dark matter halo.
