Orbit projection in the potential axisymmetric for “J131340.4−484714” (blue line) and ω Centauri (red line) in X,Y Galactic coordinates on the Galactic plane. The solar position is (X_⊙, Y_⊙, Z_⊙) = (8.3, 0, 0) kpc in t = 0 Gyr. The solid curves show the orbits integrated backwards from initial position in t = 0 Gyr (open symbols) to τ_enc = 0.2 Gyr (filled symbols) that have a close encounter with d_min< 100 pc. (A color version of this figure is available in the online journal.)
