Evolution in time of the S3 simulation of the second set. The blue and light-blue shaded areas represent the conservative and the optimistic HZ, and the blue and light-blue curves show curves of constant perihelion and aphelion, both for the conservative and the optimistic HZ. Planetary embryos are plotted as colored circles and planetesimals with black dots. The color scale represents the fraction of water of the embryos with respect to their total masses. Two planets remain within the optimistic HZ with masses of 1.37 M_⊕ and 1.65 M_⊕. They present 7.49% and 24.38% of water content by mass, which represents 366 and 1437 Earth oceans, respectively. A color figure is available in the electronic version.
