Panel a: time evolution of disk accretion rates among three hosts of different masses, based on Eq. (5) of Manara et al. (2017). Panel b: time and host-mass dependencies on disk mass based on Eq. (5) of Manara et al. (2017). The solid lines from thick to thin represent the ages of systems, from 0, 0.5, 1 to 3 Myr. The green dashed lines correspond to the linear, quadratic relation between the mass of the disk and that of the central host.The time evolution of the disks is the same around stars of all masses.
