Overview of the high-density stellar groups in relation to known moving groups. Each row corresponds to one moving group recovered through our method. From top to bottom we show Sirius, Arch/Hat, Hyades, and Hercules. Left and middle panels show distributions of stars in the v_ϕ−v_R and v_ϕ−R_Gal diagnostic diagrams, respectively. Points are color-coded by high-density group (left) and by v_R (middle), with overlaid regions indicating the locations where overdensities were identified by Bernet et al. (2024). The arches and ridges reflect how the moving groups vary with R_Gal and v_R. Right panels show the distribution of stars in the [M/H]–Age plane, color-coded by group.
