Disk aspect ratio (thickness over distance to the star) as a function of distance to the central star. Each line represents a different epoch, from 0.1 Myr *uppermost line) to 5.2 Myr, with a 0.1 Myr step. The initial mass of the disk is 0.016 M, and the lifetime is 5.3 Myr. The mass of the central star is 1.0 M.
