The growth of the planetary core up to the crossover mass accounting for envelope enrichment caused by pebble evaporation. The blue lines show the case with M_s = 1 M_⊙, t₀ = 10⁶ yr, α_turb = 10⁻³ and f_g = 1. The gray lines show the case without envelope enrichment. Panel a: time evolution of total mass (solid line), envelope mass (dashed line), and core mass (dotted line). Panel b: time evolution of the bulk metallicity of planetary envelope. Panel c: evolution of planetary masses as a function of the total mass. Panel b: evolution of the bulk metallic-ity of planetary envelope vs. the total mass of protoplanet. The vertical dashed lines in Panels c and d are pebble isolation mass.
