Ribas et al. 2014 (Astronomy & Astrophysics): Disk evolution in the solar neighbourhood: Disk fractions from 1 to 100 Myrs

A large high-quality sample of protoplanetary and debris disks in most star-forming regions within 400 pc from the Sun with homogenized and quality controlled photometry allows us to compare disk fractions as a function of age and as a function of wavelength. We confirm the typical 10 Myr time-scale for disk dissipation and give evidence for inside out disk clearing during this phase.
