Stellar spin evolution for Mref with respect to the simulation time t in years starting from t₀ = 1 Myr. Panel a shows the stellar rotation period P_* in days. The dashed black line indicates the initial period of 6 days. Panel b shows the external torque contributions (see Sect. 2.4) as well as the total torque acting on the star (black line). The blue, red and yellow line represent the accretion torque Γ_acc, torque due to MEs Γ_ME and the APSW torque Γ_w, respectively. The dashed line at Γ = 0.0 indicate the boundary between a spin up and a spin down contribution. Panel c shows the position of the inner disk radius r_trunc with respect to the position of the co-rotation radius r_cor The dashed line indicate .
