Top three panels: evolution of the distribution of the eccentricity, inclination, and the argument of periapsis of the bound (e < 1) disk particles. The evolution of the binary orbital elements is also plotted (solid red lines). The orbital elements of the binary oscillate on a timescale of T_vZLK = 62.5 kyr. Bottom: fraction of bound disk particles over time. After an initial period of rapid mass loss, the disk loses mass in periodic bursts on the vZLK timescale.
