Fig. 12
Time evolution of semi-major axis for 20 MEarth planets with individual starting inclinations ranging from i = 1.0° to i = 8.0° in an isothermal H/r = 0.037 disc. The dashed black line indicates a fit to the results with a slope of −3.45 × 10-4/orbit. The change of semi-major axis follows the trend of the change determined for planets on fixed orbits, see Fig. 3.
