Contribution

It provides the first comprehensive parameter estimation for Be star disks using a time-dependent VDD model and links disk structure to evolutionary stages.

Findings

Disk parameters vary within typical ranges.

Disk evolution timescales are characterized.

Model successfully reproduces observed fluxes.

Abstract

We investigated the properties of $80$ Be star disks, using the time dependent viscous decretion disk (VDD) model to interpret their mid-infrared continuum fluxes. Besides estimating the typical parameter ranges for such disks, this approach allowed us to relate the disk structure to its evolutionary status. In this contribution, we present a brief summary of the recently published results, and discuss some properties and time-scales of the VDD model solution.
