Accretion cross-section diameter with erosion in relation with without erosion depending on the pebble radius R_pebble for an Earth-sized planet with no atmosphere (left), with Martian atmosphere (10³ Pa ; middle), andwith Earth’s atmosphere (10⁵ Pa; right). The accretion outcome of these three cases does not differ significantly. This indicates that wind erosion of pebbles andplanetesimals, accreted by the planet, occurs at distances far away from the planet where the planetary atmospherehas no additional influence on the local gas pressure (see Eq. (2)). The semi-major axis a varies between 0.1 AU (violet) and 3 AU (red). Error bars (similar to Fig. 5) are removed for better visualization.
