Mapping final regimes of embryo masses to pebble accretion. The figure shows the masses of the embryos at 10 Myr for four different stellar masses as a function of distance. The initial masses (dashed lines) and the filament masses (dotted lines) are shown for comparison. Where the mass is below the onset mass M_on (Eq. (24)) or above the pebble isolation mass M_iso (Eq. (26)), pebble accretion would be absent (red area). Above the onset mass but below the transition mass M_tr (Eq. (25)), embryos would accrete pebbles on the Bondi branch (yellow area). Efficient pebble accretion would be possible for embryo masses above Mtr (green).
