Same as Fig. 5, but for the results of the parameter study when varying the protoplanet’s mass, M_p. The red, green, sky blue, and blue lines represent the SSP inner (solid lines) and outer (dashed lines) boundaries determined by the resonant trapping, which is predicted by Eq. (32) for j = 2, 3, 4, and 5, respectively. The coloured lines change into the grey lines once the protoplanet mass exceeds a threshold value, beyond which the accretion bands disappear (see Fig. 3).
