Left: semi-major axis mass distribution of giant planets at 100 Myr. The error bars represent the locations of pericentre and apocentre and thus show how eccentric orbits are. Asbefore, red, orange, green, blue, and purple correspond to stellar metallicities of −0.5, −0.3, 0.0, 0.3, and 0.5, respectively. The circles, squares, and crosses correspond to single-planet, multiple-giant-planet, and multiple-planet but single giant planet systems, respectively. Right: mass and semi-major axis ratios for the furthermost SCJ and its companion.
