Previous orbits of runaway stars ζ Oph and V716 Cen. Stars show the current position of the stars, yellow crosses show the position of the USco subgroup, and the black filled circle shows the geometrical centroid of the yellow dashed ellipse. The bubble centre distance in the top panel is 139 pc. Two trajectories were calculated for the binary V716 Cen, one using the radial velocity approximately + 57 km s⁻¹ (H2001; 2.8 Myr) and the other using the radial velocity − 10.3 km s⁻¹ (B2008; 15 Myr).
