Map showing the reduced surface density in the gap as a function of planetary mass for the exemplary disc evolution at 1 Myr (see Sect. 2.1.5), calculated using Eq. (11). The cyan line corresponds to the gap opening mass with the criterion Σgap/Σunp = 0.5. We show pebble isolation mass formulas from Bitsch et al. (2018) and Ataiee et al. (2018) in green and black and the red line corresponds to the thermal mass criterion.
