An empirical pipeline for determining the viscosity parameter for Be star disks

摘要

Be star phenomenology is strongly associated with their viscous circumstellar disks. Recently, models became available for the temporal evolution of these disks when subject to variable mass ejection rates. In this contribution we will discuss how these dynamical disk models, modeled with the radiative transfer code HDUST, can be used for constraining fundamental disk parameters, such as the a viscosity parameter, and we will report on an ongoing effort to model light curves of a large number of stars.
