A comparison of distributions in the v_ϕ vs. v_R diagram for three different samples of disk stars: a nearby sample of 276 453 stars at distances below 300 pc (left), its subsample consisting of 6108 stars younger than 2 Gyr (middle), and a sample of 237 660 stars at distances from the Galactic plane in the range of 400−600 pc. Complex structure, known in the literature as “Eggen’s moving groups”, is evident at distances below 300 pc. For example, the feature at (v_R = −25, v_ϕ = −230) corresponds to the Sirius moving group, the feature at (v_R = 0, v_ϕ = −220) is the Coma B moving group, the feature at (v_R = 0, v_ϕ = −200) is the Pleiades moving group, and the Hyades moving group is seen at (v_R = 30, v_ϕ = −210).
