Fig. 7: Evolution of completely vapor disks.

a Evolution of the surface density of the Moon-forming disk as a function of r/R_⊕. The purple solid line, light purple dashed-dotted line, and the yellow dashed line represent the surface density at 0 year, 10 years, and 100 years, respectively. b The final disk mass normalized by the initial disk mass for icy planets (solid purple line) and rocky planets (dashed yellow line) as a function of the planetary mass M normalized by M_⊕. For the details, see the main text.
