Evolution of binary semi-major axis and eccentricity for initial mass ratio q = 0.1 (upper panels), q = 0.3 (middle panels), and q = 0.9 (bottom panels). The blue, red, and purple lines show the simulations with e₀ = 0.05, 0.5, and 0.8 respectively. We note that we do not show the transient phase occurring within the first 100 orbits here. Therefore, e₀ and a₀ in the last column are the values of eccentricity and semi-major axis after 100 orbits.
