Radial velocity, v_r, relative to the center of mass over time and the orbital properties of the SCES runaway singles and binaries. Top: time evolution of all the runaways in groups 1 and 2. Middle and bottom: velocity (solid) and semimajor axes, a_i (dotted) of each member in the two runaway binary stars formed in our simulation. Both are from group 1. The dark lines are the primary stars, and the light lines are the companion stars. Orbital properties for each system are listed in the corresponding panel, calculated for the stable orbits after t = 0.85 Myr, which is indicated by the vertical black line.
