Comparison of minimum stable orbits with the corresponding distances from the star at which most material is eroded. Upper line (circles): semi-major axis Ro of an eccentric planetesimal prone to erosion. Lower line (squares): periastron distance Rp at which pebbles are released (2 km planetesimal and 1 mm pebbles; boundary layer from Cedenblad et al. 2021).
