Eccentricities (on the left) and inclinations (on the right) of the simulated planets around a 0.6 M_⊙ star (in green; the top row) and a 0.8 M_⊙ star (in blue; the bottom row) versus their semimajor axes. Different shades of green and blue denote the different initial values of the gas surface densities at 1 AU, i.e., 1000, 1250, 1500, and 1750 g cm⁻²; the higher initial density, the darker color of the circles. The point size indicates the masses in M_⊕ of the formed planets. Eccentricities and inclinations of terrestrial Solar System planets are displayed for comparison (in red); their sizes are enlarged by a factor of 2 for better visualization.
