Like Fig. 2 but now including the time evolution of the disk, also for α = 10⁻⁴ (left) and α = 10⁻³ (right). Evaporation line positions are shown with vertical lines, which are different for the different simulations due to an increase in viscous heating with increasing α (Appendix B). We use the same disk parameters (except α) as in Fig. 2, corresponding to the standard parameters shown in Table 3.
