Time evolution of the planet’s semi-major axis (solid lines) and planet’s core mass (dashed lines) for different initial locations. Black dashed line represents the zero torque location. Simulations correspond to a low-mass flat disk of M_d = 0.03 M_⊙ with a dead zone using R_{in - dz} = 2.7 au, R_{out - dz} = 20 au, α_back = 10^-3, and α_dz = 10^-5. Simulations stop after 5 Myr or when the planet reaches the cross-over mass.
