title = "Small magellanic cloud be stars: color-magnitude relations and mass-loss",
abstract = "We present an analysis of optical lightcurves of Small Magellanic Cloud (SMC) Be-type stars. Observations show that (1) optical excess flux is correlated with near-IR excess flux indicating a similar mechanism and (2) the lightcurves can trace out “loops” in a colour-magnitude diagram. A simple model for the time dependence of bound-free and free-free (bf-ff) emission produced by an outflowing circumstellar disk gives reasonable fits to the observations.",
