Synthetic populations of planets produced by the Monte Carlo version of GroMiT using millimeter-sized (blue symbols) and centimetersized (green) pebbles. Left: final planetary masses and semimajor axes of the planetary populations. Right: core masses (pebble isolation masses) of the planets with final semimajor axes between 0.05 and 0.1 au and planetary masses between 0 and 20 M_⊕ as a function of the final planetary mass.
