Comparison of distribution of disk masses in our population of Zone 1 planets, evolved using the model presented in Sect. A.1. We show the mass of each of the disk models at its initial time, 2, 4, and 6 Myr into their evolution, even if the disk lifetime for any particular disk model is shorter than those times. We compare to the disk masses measured in a population of class 0/I from Tychoniec et al. (2018) and to a population of class II objects from Ansdell et al. (2016).
