Evolution of the disk parameters for the models with M_* = 0.1 M_⊙. The colors show different α_visc. For reference, the viscous timescales are 0.046, 0.46, and 4.6 Myr for α_visc = 10⁻², 10⁻³, and 10⁻⁴, respectively. The evolution of the disk mass for the models with M_* = 0.32 M_⊙ and 1.0 M_⊙ is shown Fig. A.1. For the model with α_visc = 10⁻², M_disk starts out at highermass compared to the model with α_visc = 10⁻³, but this model also loses mass at a faster rate.
