Numerical growth track of the planet by pebble accretion starting at a₀ = 1.985 au and t₀ = 3.5 Myr. The initial mass of the planet is 0.001 M_⊕. The final mass of the planet is 0.68 M_⊕ at location of a = 1.0 au. The starting point of the planet is indicated by the square. The circle shows the final position of the planet when the disk dissipates and the planet stops migrating.
